Seiko World Timer - Ref 6217-7000

In today's blog we take a look at a lovely vintage Seiko world timer from one of my returning customers. This model was actually in pretty good shape all things considered but there was a little work to do to bring it back to its best :) Lets crack on......
​

Years of dirt and grime, ultrasonics will take care of this. The oscillating weight is loose :(

Crystals seen better days and although it could be skimmed and polished i think new is better.

Stripping down the movement is fairly straight forward and so i won't bore you with over details and just cover the important bits :)
​

Quite common with Seiko movements is this hardened black grease, this in turn wears away at the plating :(

Every once in a while you may find the oscillating weight can come apart, not just on Seiko's but other automatics as well. Most occasions its best to replace them outright, but sometimes with a little tlc you can repair them back into working order.....
​

Original rivets have loosened over time making this rotor not function at its best.

Using a staking set and punches we can re-tighten the original rivets and complete the rotor again for use. No problems here so ready to go !

During movement service the casing is stripped down and ultrasonically cleaned prior to polishing.

With the casing being cleaned i set to work on rebuilding the movement, checking each component for damage and where needed replace parts. During assembly each small system is checked before adding the next stage, by double checking at each stage you can identify problems early on rather than having to strip it down again later.
​

Movement complete and running very nicely, now to leave for 24 hours before adjusting.

Early results show promise, once running for a few days this can then be adjusted for best accuracy and then cased up :)

With the movement complete and running nicely the case work was then the next stage, taking care not to ruin original lines a light cosmetic clean up was the order of business. As the casing was cleaning after polish we re-dial the movement and fix the hands in place, this stage we also check the hands are moving correctly.
​

Hands fitted and everything is ok so time to re case the movement !

Movement nice and snug we can fit a new gasket to keep the moisture out.

With everything complete the watch is now ready to go home and be enjoyed once more. :)

Vintage Seikos are always a pleasure to bring back to life, this model has a most wonderful silver cloth dial mixed with contrasting black & blue print of the 24 hours zone and the orange ring denoting the cities. Overall i was very pleased with this watch, both timing and finish were really good and i was happy to send this one home :)
