Job Number 200024, Elgin Grade 494

Here we have an unusual Elgin, a grade 494, 16 size, 23 jewels, made about 1934. It is lever-set and features a motor barrel and up/down indicator.

There was a minor issue right from the start. It’s hard to see but one of the head of the dial screws is split in half. Fortunately I was able to reach in there and turn it out.

Over-tightening of screws in watches is a very common problem. In the case of dial foot screws, it’s the main way dials get cracked. Tightening one, literally, until the head breaks off is just off the charts.

Two very thin steel gears under the barrel transfer rotation from the gear stack to a larger brass gear that sits under the dial, all for the up/down indicator.

Here are these two parts in place. The cutouts for these parts are what makes a 16 size Elgin with the up/down complication stand out.

These parts make up the rest of the up/down mechanism.  A cleverly designed stack of gears transfers revolutions of the mainspring barrel arbor to an “up/down indicator” sub-dial that reads how much the watch is wound.

Someone scribed an arrow on the side of the mainspring barrel. I assume they meant to remind themselves which way the spring went - which a little odd. It only goes one way.

By far the best way to be sure how things fit together is to fully understand how the watch works.

The motor barrel… This is a 23 jewel watch so the barrel arbor is jeweled bot upper and lower. 

Just above the ‘O’ in “positions”, you can see the upper pivot of the up/down gear stack.

If you zoom in, you can also just make out where the top of the gear stack meshes with the ratchet wheel to move the up/down indicator when winding, just below “tions”. 

On the dial side a larger brass wheel ultimately drives the indicator. It is meshed with the very thin gears under the mainspring barrel.

Note the extra hour wheel-like part. It sits on a fixed post and holds the wind hand.
