I have this Seiko Dive watch that belonged to my brother who has passed.

The number I see on the back is 920060. I am trying to find someone who can repair it or install a movement if that's possible. I do know it is a perpetual movement and that's it.

Any help would be greatly appreciated. This watch has a lot of sentimental value and I would love to be able to wear it.

The watch has an 8f35 movement.  8F35-0019 is the exact model number and will the most results in an internet search.  The marketing number is SLR001.  8F35-0019 is the number you use when looking for parts. 

I don't have a perpetual calendar watch but I do know that it is tricky to reset after a battery change.  The battery is supposed to last 10 years.

Hi  I have attached the service sheets for this watch. There is a section on battery changing, Its got to be completed within 3 mins as it erases the calendar data.  so before removing the battery obtain another to effect quick change. Also do not short the battery on fitting as this will have the same effect.   Read the sheets before attempting the change.

Always worth to remind quartz watch owners that their stopped piece will likely work again with just a battery changes, but that is not guaranteed either.

To reset the calender the below video by our host Mark Lovick as an alternative to official guides

I presume by perpetual that the watch knows when a leap year occurs? I would love to know how they do that?

As explained in the document and video above you set the number of years elapsed since the latest leap year. 

If the battery is replaced when the watch shows its time to do that, it is not a necessary to go through the reset procedure.

      That’s a nice idea, But i’m committed to providing this site as a gift to the watch repair community as my thank you for my incredible life i’ve had in this business. Ive done well and unless my financial circumstances change then i’m more than happy to foot the bill. If circumstances do change then be assured that I will make an appeal. For now, I’m comfortable with the way things are and I am extremely delighted to remove Google Ads from this site and to stop Patreon, it feels like a major step forward 🙂 Sorry, I missed your reply, I got blinded by another poster in this thread. Yes - I can confirm that I have always seen WRT as a not-for-profit website, and therefore - not a business as such. I’m lucky and have done well in my life due to a decision made in my teens to start a watch repairing apprenticeship which has sustained myself and my family for many years now. Consider this my small way of paying it forward. Ive been committed to keeping the site alive on a technical and financial level for over 10 years now and I have zero plans to change that. Thank you for your kind words by the way. And as for your wish - nobody can control what happens in life, if something happens to me I have things in place with my family but I’m just not comfortable talking about my personal business - I wish a certain person would respect that, but i’ve calmed down now - i’m only human 😄

      Yes, exactly. I've seen a few different versions, but mine has the blue water symbol, not white.    I think it's Acrylic. The case is plastic so I would the is the lens would be too.

      From the same listing, the back side: I would guess that the back pops off rather than the front. You can see a little groove there where the caseback sits over the winding stem, rather than a case tube. Look for an indent or notch around the back. It might be possible to pry this off from almost anywhere on the back if it sits right against the rubber strap. The movement looks like it is from the Ronda RL family (015 or 115 or something? I forget which numbers have a calendar and which don't)

      I'd expect a similar notch somewhere around the rear to pop that off.
