Historical Horology: Servicing A Vintage Watch




Servicing a watch is much like having your car worked on – it’s something we all know we need to have done, somewhere in the back of our mind. Even with that, though, we often put it off as long as we can, or we’ll let the watch sit in the back of the drawer for a few years until we get around to sending the watch in, or taking it to our local shop.

What if your watch is something a bit more unique, say, like a Grand Seiko? Over at Professional Watches (here), Jason Pitsch recently sent his 1967 Grand Seiko back to the motherland for servicing (that’s right, directly back to Japan). While he wasn’t surprised to learn that the watch had a broken mainspring, he was surprised by Grand Seiko Japan’s response.

What they said, basically, was the watch is over 40 years old, and is not expected to be serviceable, and they would not be able to repair it. Now, I know that the mainspring is one of the more critical components, but you’d think something like that should be replaceable. Of course, Grand Seiko is in the clear (kind of) as their own documentation states that you’re only guaranteed parts availability for about ten years.


He then tried to take the watch to a local watchmaker, who believed he could likely source a suitable replacement, if he knew the specs of the spring. Unfortunately, somehow the Seiko service department has no details on the specifications of that particular part. This is an unfortunate thing, because we’ve come to expect that high-end mechanical watches are something that can be maintained for decades and eventually passed along to another generation.

In fact, that’s something that many Swiss and German firms tout very highly. And yes, it does help that for watches utilizing more common movements (say, the ETA 2824) that many more third-party watchmakers are familiar with them, and can readily work on the movement. Rarity of a movement shouldn’t make it impossible to repair, though. More difficult, especially due to the age? Sure, I get that – parts are harder to come by.


While long-term serviceability (or lack thereof) doesn’t necessarily mean that the watch in question is of any greater or lesser quality today, for sure. However, if you’re looking to pick up a piece that will be handed down to grandchildren, or you’re perusing for a steal on a vintage piece that needs a little work, it’s something you’ll want to keep in mind.

Thank you for reading this WristWatchReview post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

WristWatchReview is one of the few remaining truly independent watch news outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent watch sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis. We don't play the games the other sites play and we've paid for it when it comes to ad revenue.

We would love for you to support us on Patreon and every little bit helps. Thank you.
