A7750 with a Interesting Feature

Recommended Posts

In the processes of wrapping up a full service on a members watch. I noticed some thing unique with disassembling the movement and figure I would do a write up on this during the assembly. I would like to know if any other members have come across this

I first noticed this modification over 2 years ago, it's random, some newer movements are upgraded, some aren't...and you are correct, it eliminates the datechange problem.

There is a simple test of an assembled movement to find out if you have this upgrade, turn the hands forward until the date changes at midnight, then turn it backwards to 10 pm or so, if the date DOESN"T change on the backwards movement past midnight, you have the upgraded gears.

Great photo's, thanks for this...

Great find :thumbsupsmileyanim:

So is this available on all new A7750s?

:evil2:

I think it is hit or miss regarding what movements this is on. As Z, said, he came across this about 2 years ago. The watch i am working on, is at least a year old if not more.

Z, I was hopping you would chime in as I figured you of all people would know about this! Thanks for chiming in!

Do you know if this a Asian Innovation?

I believe it is, having never seen it on an ETA. It is a good idea, now if they would only fix the rest of the design issues... :)
