Life of Watch 3 Months In Southwest Pacific
The necessity of channeling 2,600,000 wrist watches, with movements 8 3/4 ligne or larger, to Army post exchanges and ships' service stores in 1945 for resale to service men, and possible methods of assuring that importers can meet this requirement were discussed at the recent meeting of the American Watch Importers Industry Advisory Committee, the War Production Board reported today.
The average life of watches used under battlefront conditions is extremely short, military representatives emphasized. They said that a watch lasts only about three months in the Southwest Pacific, and somewhat longer on the European front.
Currently, under Order L-323, WPB assigns for distribution to the Army Exchange Service for Army and Navy resale 50 per cent of all imported, men's wrist watches with movements 8 3/4 ligne or larger and 50 per cent of all uncased movements in the same size range.
Committee members estimated that importation of watches and movements in 1945 would total between 5,250,000 and 5,500,000 units. Of these about half are expected by the committee to be men's watches. Since only 50 per cent of those suitable for military purposes, or less than 1,350,000, would be channeled to the Army Exchange Service under present WPB policy, military requirements could not be met, committee members said.
The difficulty of meeting total 1945 military requirements for imported watches was emphasized by committee members. Since watches normally cannot be delivered from abroad until about a year after they have been ordered, they explained, orders for increased quantities that might be placed now could not be delivered under 1946. Committee members pointed out that transportation difficulties and the scarcity of raw materials are additional complicating factors in the commerce between Switzerland and the United States.
The possibility of placing military orders for imported watches on a firm basis, by means of long-term contracts, similar to those placed for most other types of war goods, was discussed. Committee members said that orders from individual post exchanges and ships' service stores, since'they provide no guarantee of purchase, offer importers no protection against possible cancellation of orders following the defeat of Germany.
Military representatives emphasized that requirements for watches are expected to remain high until both Germany and Japan are defeated. They said, furthermore, that while it might be possible to place procurement of imported watches on a contract basis, importers then would be required to meet definite delivery. dates. Committee members said that the uncertainty of delivery of watches to importers would prevent them from meeting such contractual obligations.
Committee members mentioned that the supply of repair and replacement parts for civilian's imported watches is improving. They pointed out, however, that repair service is limited by the decreased supply of manpower.
Then the roller table and hairspring are then installed and the balance assembly is complete.
WPB has declared a blanket MRO (Maintenance, Repair and Operating Supplies) rating invalid for clock and watch repair materials, including mainsprings, and does not contemplate assigning any preference ratings for such materials on Form WPB-541, WPB representatives told committee members. This section was effected by amendment of Priority Regulation 3 on June 23. 1944, they said, and is expected to result in more widespread distribution of clock and watch repair materials.
The continuing: need for increased quantities of railroad watches for use by railroad time service employes was emphasized by a representative of the Office of Defense Transportation. Unless the labor shortage in the industry increases in severity, deliveries of railroad watches are expected to be stepped up in the latter part of 1944, industry members said.
The time required to make railroad watches, they explained, averages about nine months. Increased demands therefore cannot be met quickly.
The problem of maintaining production of watches for the armed forces was also discussed. lAC members emphasized the importance of receiving orders at least six to nine months in advance of the date on which delivery is expected. The many operations required in the production of a jeweled watch are performed over a period of six to twelve months, they explained. Each operation requires a special skill, and workers cannot be shifted from one department to another. This means that at least a skeleton force must be maintained in each department. Unless orders are scheduled long in advance, workers in all departments cannot be kept busy at all times, and they may leave for other jobs. If the staff of any department is depleted, operations in that department as well as all succeeding operations, are delayed, and delivery of future orders is jeopardized, committee members said.

If after prolonged use the bath becomes cloudy owing to the presence of foreign matter deposited by the parts which have been immersed, all that is necessary is to pass the liquid through filter paper to restore it to its original condition.
Unfair Market practices Stopped
The Hamilton Watch Company complaint was supported by an affidavit by W. Ross Atkinson, Vice President of the Company. It named the defendents as Hamilton Ross, Harry Zeidler and Henrietta Ross, co-partners, doing business as Hamilton Ross Industries.
Hamilton Watch Company has won favorable court decisions on several occasions in recent years. Each time action was taken when the fine public acceptance of Hamilton Watches was challenged by unethical market practice by outside interests whose product promotions tended to confuse the public and infer such products were related to Hamilton products.
This constant vigilance to protect the name and· fine reputation that has been built through more than fifty years of successful merchandising of "Hamilton, America's Fine Watch," is assurance to the retail jewelers of America that their past investments in Hamilton are being safeguarded-that in the future finer Hamilton watches will continue to be potent with profit possibilities for them and set new standards of performance to assure even greater public satisfaction.
New Transcontinental Speed Record Set By Two Army Planes, Timed Exclusively By Longines
The official time as taken from a Longines stop watch which passed timing tests according to the rules and regulations of the Federation Aeronautique 'Internationale according to the Neuchatel Observatory Bulletin was 3:32 p. m. Eastern War Time, and exactly seven minutes later Lt. Colonel Jack Carter arrived in the same type plane, after making a non-stop flight.
Colonel Carter, who lost five minutes circling over the Los Angeles airport to check his retracted landing gear.
It took almost seven years to beat the record established by Howard Hughes in 1937, when he flew from Burbank, California, to Newark in 7 hours and 28 minutes, averaging 327.1 miles an hour. The epochal flight of Howard Hughes was also officially timed in 1937 with Longines watches, which are the only watches available in this country with the proper Certificate of the Federation Aeronautique Internationale Bulletin, issued by the Neuchatell Swiss Observatory.
John P. V. Heinmuller, President of the Longines- Wittnauer Watch Co., Inc., is also Chief Timer for the National Aeronautical Association. He was assisted in officially timing this flight by Fred Wilkinson, who acted as Timer for the National Aeronautical Association.
Following the last war Mr. Heinmuller helped organize the Timing Contest Board of the National Aeronautical Association, in harmony with chronometric specifications of the Federation Aeronautique Internationale and became Chief Timer of this organization, the position he still holds today. Among the outstanding flights he timed with Longines watches were those of every major wor1cl record established in the last fifteen years. Mr. Heinmuller's new book "Man's Fight to Fly" with the chronological history of aviation has just been published by Funk and Wagnalls. It is heralded as the most outstanding aviation book published thus far. These one motored fast pursuit planes called "MustangP-51" will no doubt in the near future fly directly to Europe. The plane has a wing span of 37 feet and a four blade propeller. It can travel 30,000 feet high at which approximate altitude the Transcontinental flight was made.

The Separation of Static and Dynamic Beat
By Emanuel Seibel
What is good mechanical condition, you may ask.
First, it must be clean. Then we must have positive train freedom, but this freedom must be correct, not because pivots are sloppy but endshakes and sideshakes must be correct; these pivots must be well polished. Wheels must be absolutely round. Barrel arbor must fit as snugly as possible without bind. Center wheel must be upright; all wheel teeth straight without burs; pinions polished so that all frictions are reduced to a minimum.
Then your escapement must be set up as light as possible with safety.
Drops equal, lock and slide as light as you can make it, draw positive.
Roller jewel properly fit to fork slot and your guard sure, and the closer you can make pallet and balance shakes alike, the better you are off.
Now we are ready for poise. Most watchmakers poise to a square that is four points,-some to eight points or a double square. First, the balance must be absolutely true, round and flat. Before we attempt for poise, if the watch has the original staff in it, it should not require much, if any, poising; if a staff is being replaced, and old staff is turned out of wheel and properly staked fast, it should not need any, or very little, but poised it must be.
When you are satisfied it is as close to poised as it can be ,gotten, you have your static poise, or poise in rest.
Now, you put on your hairspring and your static poise is disturbed because your collet, to begin with, is not poised in itself and cannot be, for it has a slot in it, and if it is not a proper fit to Hairspring shoulder and is forced on staff, it is spread and the condition is aggravated.
The spring, which is spiral, cannot be poised. Remember, the wheel itself is in poise at rest, but the complete assembly of wheel and spring has disturbed this static poise and we must get this assembly in dynamic poise (that is, in poise under power, or in motion). This is where the Watchmaster comes in.
Now, remember, the Watchmaster will not do it, and cannot do it. It can only indicate the trouble; and how you may correct it, is in your ability to interpret the readings of your Watchmaster and make the indicated adjustments.
Your balance under motion to function properly must have a turn and a quarter of vibration and we find that unless the hairspring is properly centered, positively true in round and flat and the pinning point correct so that it developes correctly, and breathes as it were, equally in all directions, you have unequal pushes and pulls in the spring, which disturb the rate and beat of your watch.
Just because your fork and roller are absolutely in line and in the absolute middle of the bankings, does not indicate that it is in beat, for the relationship of your pallets and roller may look correct in static condition, but when power is applied, your balance may pull to one side or the other and not start, and until you get this relationship of pallets to roller correct, it will not pull equally to either side and start. When this is correct, a watch in good mechanical condition will start off at the first twist of the crown.
After a balance has been poised on a poising tool, equally weighted at every degree of the circle, balancing perfectly in all positions around the axis that balance is in "Static Poise" or in a state of equilibrium. (See Page No.6 in the Book. "12 Thousand Hours").
Counter poise, in the "Static Sphere" means you actually take off or add weight.
The average watchmaker will use four corners, or one square when poising a balance. The more critical workman will use eight corners or two squares. (See Drawing at Top).
It is true that often in poising a balance you start with the screws that are too far in to the center, and when you do this the balance will be under-compensated; naturally if you start with the screws that are too far away from center the balance will then be over-compensated. You must have compensation in "Static poise" or balance that will match as near as possible, the ability of hairspring in "Dynamic Poise", after you have this combination you never destroy static poise by moving or changing screws.
After hairspring and collet have been added, and placed in watch, we then have the "Moving Element", when this, takes motion we are then concerned with "Dynamic poise".
(See Page No. 6 in the Book. "12 Thousand Hours").
Counter poise, in the "Dynamic Sphere" means, control of equilibrium in motion, and the control of this force is attained by changing the level of hairspring and push and pull under dynamic power. (See Page No.7 in the Book. "12 Thousand Hours").
Take a look at simple drawing at top. First we use the "Static Poise" and accept it as being correct. Then we check the watch on the Watchmaster. In motion we see the rate is good in all positions except P. R. & P. 1. Records show P. R. 5 Sec. slow and P. L. 5 Sec. fast. We instantly know that the "Push & Pull" of hairspring are not equal at these positions, where the "Push" develops towards the rim more than the "Pull", at that position the watch will run slow. Naturally at opposite position the watch will run fast. You simply cause the hairspring to have same ability in both positions. You do this with "Dynamic" counter-poise and NOT by changing screws and distorting your already correct 'static' counterpoise.

WATCHMAKER LICENSING AND AMERICAN NATIONAL RETAIL JEWELERS ASSOCIATION
B. W. Heald, Jeweler Milwaukee, Wisconsin
The records of ANRJA do not show any reversal of this endorsement and I understand from other officers that the President is expressing his own personal opinion and not that of the Association. Also that he is opposed to any and all regulation, activity urging the repeal of Regulation Wand all governmental regulations. It is not clear whether this opposition extends to the Federal Constitution, the Bill of Rights and possibly the Ten Commandments.
It is very apparent that serious, possibly irreparable damage has been done to the program of Watchmaker Licensing and that this damage has been done in the name of ANRJA. As a member of that Association, I protest the misuse of the office of President.
