Please see my other listings for more Services, Seiko Sales & Parts.
This listing is for owners of a Seiko SKX007, SKX009 or SKX013 automatic Dive Watch who want to upgrade/modify their watch or their watch is due a service.
Although you already own an awesome watch with an excellent calibre, 7S26. Have you ever wanted synchronise your watch? I know I have. The trouble is the 7S26 native to the SKX range doesn’t have the hacking feature need to do this. 


And if your lucky enough to own 2 Seikos with 7S26 movements it can be a bit of pain swapping between then as you sometimes have to wiggle the watch in your hand for 30 seconds to get the mainspring to charge up a little so the watch starts ticking.
Seiko upgraded this movement and called it the 4R36 this takes care of the two downsides to your current movement listed above. Seiko under another name, Hittori, produce this movement for the open market and it can be fitted into your watch to include these features.
In need of a service? If you are not precious about the movement and your all about time keeping and feature rich details then this may be the time to upgrade, you also get a really cool S signed crown fitted and an upgrade will more than likely be better value than a service.


Looking for additional mods to go with your upgrade? Please let me know what you require.

The price includes a brand new movement, “S” signed, or not signed crown (worth over £), stem and labour.

Your watch, case & bezel will be refinished at your request for no extra charge. It will come back looking as good as new provided you do not have any major dents or dinks. However these will be softened and almost hidden out of sight.

The movement will be regulated to the best accuracy possible, typically within 10 seconds per day.
6 Months Warranty on all work.

Upgrade for your Seiko Dive watch.
