Seiko 7A38 - by the numbers

Hello there,

What are the part numbers for the pusher and crown for 703b model? And what other models have same parts so I can hunt them down.

Or any member of this forum if you have spare parts I would gladly pay for them.

Also I did my own bracelet cleaning and tightening up links, it started to disassemble during wearing. Now it's good and clean.

The Seiko part numbers for pusher button and crown for the 7A28-703B (and -7039) are 80600529 and 45M54NS1 respectively.

The pushers are used on other 7A28-703x models and the same crown is also used on the 7A38-701x models.

Unfortunately, both pusher and crown are obsolete and no longer avaiable from Seiko. I can't offer any help with a substitute for the pusher, but Seiko crown p/n 45M74NS1 (used on the stainless 7A38-7270 and others) is still available and would work in its place.

If I remember correctly, the only (barely visible) difference is less than 0.5mm in the height of the knurling.

Thanks for the info. I will track ebay to see if something will show up.

Next thing to do is crystal polishing, it will be done next week.
