dial dot

 Dial dots are this sort of stuff, available with paper backing on both sides for handling and applying.

They do add some thickness, about 0.25 mm when finally compressed in the case, not enough to interfer with hand, unless the watch had abnormally tight clearances to start with.

The main concern is keeping the dot off anything that moves on the front side of the movement.

on ETA 2824 and 2836 you can just glue directly to the spacer ring and don't need the feet.

Hangzhou 6311 Seagull ST2100

Seagull ST2100

My estimate is that these two movements, the Seagull and the Hangzhou are priced about the same. The additional work done on the Seagull to decorate the external features is compensated for by skipping minor non-essential work in unseen areas. While the Hangzhou maintains a uniform dull workmanlike finish everywhere.

Also, the Hangzhou is manufactured more like the ETA than the Seagull, every part and almost every machine cut is the same on the Hangzhou as on the ETA. It just has three more jewels (for a total of 28, same as the Seagull.)

The Seagull, however, is not "just a copy" of he ETA 2824-2. It is a re-engineered version of the ETA 2824-2. Unnecessary, wasteful and difficult processes have been removed and a more simplified process put in their place. This is another way Seagull can spend more time on making the outside pretty, without increasing the production time and thus controlling the cost.

Which one would I use in a watch, if I were to make one (on a mass scale)? The Seagull.

Now, you may ask why would I pick the one that I have just ranked the lowest for my choice. There are several reasons, not the least is the name "Seagull," which does carry some weight, in that it is known as a quality movement producer. The second reason is the Seagull just looks so much better that the poor plain Hangzhou. And third, there is no real performance reason not to. The Seagull is just as clean and nice where it matters as either the ETA or the Hangzhou.

General notes on the overall design of the 2824-2 - The 2824-2 is the end of a long and involved evolution of movements. The end requirement was, apparently to make the least expensive movement possible, while maintaining reliability. Just about all of the springs are integrated into the parts that need them, this makes the 2824-2 one of the easier movements to work on.

By using the design of the ETA 2824-2, the Chinese have copied one of the best (affordable) movements offered by the Swiss today. It is not a vintage Elgin, from say, 1950, (the pinnacle of movement making, in my opinion) or a Rolex 3135, but then these movements don't cost what an Elgin did in 1950, or what a 3135 does today.

Provided the watch manufacturer keeps fingers off the balance wheel and dust and debris from floating around the inside of the case, either of the two Chinese movements should provide an excellent engine for any watch.
