looking for correct mainspring for Seiko 2906


Recommended Posts

Hello, new to this hobby and need help with sourcing the correct mainspring for a seiko 2906. barrel measurements, 7mm diameter, 1.5mm height, 0.2mm lid, i get an approx mainspring spec of 1.2 width, 0.08 strength and 245mm length. Looking through cousins site, GR2593X seems the closest. is there other recommendations of places i can source a mainspring for this seiko 2906 in canada?

Maybe not directly in Canada,..but got to Emmywatch.

She has a database that shows any of her linked "partners" for parts availability. Many of them are from Ebay. I've found a lot of parts I've needed this way.

Jules Borel in the US also lists mainsprings for that caliber.

Another option is a scrap movement - the 2906 is a very common type on ebay.

I've had a few batches of Seiko movements from this seller in Holland - they are presently listing a batch of six incomplete 2906's for around 16 euros, or three complete looking ones for a similar price.

(Quite a few of the apparently complete ones I've had came with visibly bent balances.. A good excuse to add truing pliers to my gear!).

    • Thank you for your introduction and welcome to this friendly forum. We all look forward to your contributions and continued involvement. 
    • Have you now repaired it? If so how is the time keeping.
    • Yes: that's it exactly, right down to the break in the spring!!
    • I've bought brands like Citizen, Seiko, Titoni, Tissot, Roamer. Strange thing is many of them were using ST96 movements. I'm not sure if the ST96 is original to that model or whether it was a replacement movement.  All the watches with nice looking dials were obviously refurbished, after-market dials. And all of them had over-polished watchcases. Some of them had non-original hairsprings, rejewelled pallet forks, watch crystals that don't fit and glued in with a generous amount of glue. One of them was totally not working because the pallet jewel was loose to the point that it almost fell off. But the sellers were very nice. The seller of the non-working watch gave me a complete refund. Some of them gave partial refunds. I would say don't by luxury watches on the internet, regardless of the country the seller is from. Don't believe the "serviced by master watchmaker" statement. Have realistic expectations. ( Do expect the occasional complete junk.) Do expect to do a complete overhaul and major repairs. Otherwise, watches from Mumbai are great. For clocks.... I'm not so sure.
    • In 2020,I picked up an Orient Mako II online. It ran at +15 seconds per day and after 3 years of resets more than weekly, it was time to crack the seal and take a shot at regulating it. Not having a timegrapher, I used a spreadsheet to track the time, referenced the Canadian NRC website, wore the watch between adjustments, and used the back end of some tweezers to lightly tap the regulator daily until it ran to within one second per day.   Two months later, it’s still running to within 1 second per day when measured over a week or longer, while daily variations are up to 9 seconds per day. For my purposes, its overall stability is surprisingly good. Is this method of adjustment “better” than adjusting to 5 positions using a timegrapher, since during the adjustment period the watch is already in the environment in which it’ll be used?
