Alan sent me this interesting Damas GSTP Military Pocket Watch for repair and service. The watch was a non runner and also required a crystal replacement.
GSTP stands for General Service Trade Patterns, and designates watches which were issued to the military forces during the World War Two era. I always like to work on old military watches, it is a nice feeling to have a piece of history on the bench.
This particular watch is signed “Damas”. Other manufacturers also produced GSTP pocket watches (e.g. Buren, Jaeger Lecoultre, Leonidas…), with different movements but all are very similar in appearance (large dial Arabic numbers designed for legibility, subdial for seconds hand at 6). This, in my view, makes them very interesting and collectable.

Today I decided to feature this Seiko Kinetic 5M62-0BL0. It is in need of a capacitor replacement. I will go through the various steps in a bit of detail, as some of my readers may be interested in attempting this themselves. Hopefully this narrative will be of help.
The procedure is achievable for a keen DIY-er. How far one takes it will depend on the level of skills and equipment. A simple capacitor replacement can be done with the movement in situ. However I personally choose to remove the movement to give the case a thorough clean without any risk to the movement. I also pressure test the watch after re-sealing it to ensure that the water resistance has not been compromised.

I have already featured several vintage Longines on the blog, so I thought I would write a post about the service of this “modern” Longines Hydroconquest. It is an Automatic Diver’s watch, powered by Longines’ calibre L633.5. As you will see, this movement is actually an ETA 2824-2.
The watch looks very smart indeed, and I am impressed by the build standard, it has a real quality feel to it. It came for a service. The crown was very stiff when winding or setting the time, so I will be investigating this as well.

This Omega Calibre 1030 was in need of a service. The watch was manufactured in 1978. It has a 9ct solid gold case, which is a “front loader” design with no removable case back, like many Omegas of the era. I think Omega produced some of the best dress watch designs in the 1970’s, and this one is a very good example, elegant and timeless.

This Waltham pocket watch required a service and crystal replacement. It was running, but not very well at all, timekeeping was out by several minutes a day and the balance wheel had very poor amplitude.
It was approximately 81 years old at the time of writing: Production dated year 1936, according to the Waltham “Gray Book” List.
The watch is in very good condition given its age. It is cased in a gold filled case by British maker Dennison. This particular case is made of a base metal sandwiched between two plates of 0.036mm thick 9 carat gold. It is their “star” grade which at the time was guaranteed for 10 years. The quality of the plating by Dennison has stood the test of time as it is still in good condition, with very little base metal visible.

This week I decided to feature the restoration of this Blancpain Calibre R540 watch. I could not resist a “before and after” shot in the introduction, but the transformation on this watch is far from being just cosmetic. As you will see there was quite a lot of work required to bring the watch up to a fine condition. It has been a very interesting project, and it has been a pleasure to work on a vintage piece by such a prestigious manufacturer in the history of horology.

This week I have decided to feature another vintage Longines as they are such a pleasure to work on. This particular watch has a 9ct solid cold case and caseback, and it is powered by a Longines Calibre 284 movement. Very much like the Calibre 12.68Z I featured on the blog recently, this movement is from an era when Longines were very much at the high end of the market. The level of finish is very high.

When my friend and fellow horology enthusiast Andy showed me this old Jaeger cockpit clock I was immediately intrigued and interested. It was a complete non runner, and I had not worked on one of these before, but being a classic car enthusiast myself I was very keen to work on this piece.

This lovely vintage Omega Seamaster came in need of a service. The watch was not running very well.
It is powered by Omega’s Calibre 752. The serial number dates the production of this watch to 1968, it looks well preserved in appearance.

The Seiko 6309-7040 diver’s watch is one of my favourite watches. I have worked on many of them before, and have owned several myself. When my friend Ed got in touch a few months ago about a project involving a large number of 6309s and a box of spare movements, donor watches and other parts I was of course very interested indeed.
Ed and I met up and we went through all the watches and movements on my timegrapher to get an idea of the health of each individual item, and decide the best course of action.
Unfortunately due to the magnitude of this project I have not had the discipline to take enough photos to do a detailed walk through of the work, it is so easy to forget when you get stuck in.
I do however have some photos, so I thought I would publish them to give you an idea of some of the work involved. After all it is not often you see so many 6309s in one place!
Here is a photo of the project once completed:
