Well, it's keeping really good time so far. Lost about a minute overnight. Sadly I don't know where the screw is that you mention and I don't have a spare but, I checked the other one and it is tight. I have put it back in it's case and I suppose I will reluctantly have to give it back to it's rightful owner. I wish it belonged to me as I am quite taken with it, it is a lovely little clock. Here are a couple of final pictures of it complete and ready to go home. Thanks very much to everyone for their help, advice and comments without which I doubt I would have got very far. I am quite fired up now and might have a look and see if I can find a little clock for myself as a project.

I bought the cheapest pair of glasses I could find (from Aldi), pushed the lenses out and fitted the clip on lens to the arm. Works a treat and I find it much more comfortable than a loupe.

Hi All , I went to the Swap meet at Aloha stadium today and found this Seiko 6117-6409 World Timer made in Feb. 1972 . It's running and keeping time so far . The inner bezel with the cities rotates as it should and the GMT hand is also working . It has a Linen Dial and the watch is in good overall shape . The only flaw I can see is a scratch in the acrylic crystal that I can easily clean up but I made a bid on a new Seiko crystal . It has a generic expanding watchband , but I may get a dark blue leather or blue suede watch band . I'll look around for that and see what suits the watch ............I was able to pick it up for under $50 .

Hello andycfair and welcome to the forum. I'm a qualified watch/clockmaker but have been retired for many years, if I can help in any way with clocks just ask.

Thanks Geo. A little more. I bought this quite smart case with display back as I liked the crown guards and that it's only 42 mm. It still makes a huge watch as it's all dial. Anyway, the hands were delivered with C1 lume (the white one which was what I wanted) and the dial with C3. That had to go back which was during their company holidays..... So, thought I'd pressure test the case. It's rated at 50m or 5 bar (75 pounds per square inch, psi) so I tested at 25% above that. Here with the case above the water and 6.25 bar showing (92 psi). If the watch leaks, then the pressure inside it equalises to 92 psi and when the pressure in this plastic cylinder is decreased, the air will come out of the watch so, before releasing the pressure, it goes into the water. Then, bubbles will be seen. None showed here as the pressure was slowly released so, it seals fine. I forgot that picture. There is a big problem with these sort of testers. If you drop the pressure quickly and the case has let in that pressure, then you can blow the crystal out submerging your nice rebuilt movement in the water. So, I always test first with an empty case. I've had one crystal blow doing that.... Just thinking of the force involved, this crystal has an area of about 1.5 in2 so, if there was a delta pressure of 92 psi, that would be nearly 140 lb. I usually push old crystals out from behind with my thumb so, they would clearly pop out under a tenth of that force. Anyway, it's slowly coming together! Cheers, Chris
