More New Stuff – S-510 Tool for SEIKO 7016/7017/7018 Chronographs

By February 18, 2019Uncategorized

Geday Everyone,

After a much delayed development I am pleased to announce I’ve finally released the S-510 tool, which replaces the old SEIKO S-510 and S-511 handsetting tools.

Differences from the original are that the pushers are captive and having an adjustable dowel means that one tool can handle all the movements.

The extra dowel was deleted as it is not required, it doesn’t actually support anything because the bottom bush for the minute counter wheel is hidden under the winding wheel.

I have the tools available on Ebay. The first 10 will be supplied in gold.
