Service: Zenith El Primero Power Reserve 03.0240.4021 / calibre 4021

We’ve done quite a few El Primeros here at the workshop, but never the calibre 4021. The 4021 is a modification of the calibre 400.
Instead of the hour recorder and date, the 4021 has a pretty nifty power reserve indication. On top of that, the movement is skeletonised around the balance and escapement, so that these components are visible through an opening in the dial.

The dial looks a bit Breguet-like, and there is of course no hour recorder as on the calibre 400.

This watch was sent in from Lithuania, just to make the whole thing a bit more interesting 😉 Continue reading

Service Breguet XX (20) / Valjoux 225

p1030146We have settled into our fabulous new workshop, and are very happy with the new environment…

Andrew sent us his Breguet XX, as the hour recorder wasn’t working. The second and minute recorders work fine, but the hour recorder just won’t budge…

The Breguet XX was developed after the war, and was issued to the French Air Force. The Vajoux 225 movement is based on the Valjoux 22, which doesn’t have an hour recorder, so that was added to the bottom plate for the 225.

Service: Lemania Chronograph RN Nuclear Submarine Series 3 / calibre 2220

IMG_0663As regular readers might know, we sometimes invite customers into our workshop if they would like to see what we do, and if the watch is something special. Chances are even better if the watch has an interesting story, and Tim ticked all the boxes, so we invited him down from Scotland to our workshop.

In this photo, you can see the Lemania (and Tim) on boad HMS Valiant at the periscope around 1984. The watch was issued to him in 1983 (it was made in 1964), and he has had it ever since.

The interesting bit about the watch is that it’s a special issue for nuclear submarines, having no luminous compound (as radioactivity is tightly monitored on board nuclear subs, for obvious reasons), and a white dial with black hands. Continue reading

Repair: Omega Seamaster 105.004 – 64 calibre 321

P1010354When Vincenzo sent me an email asking if I would put together his Seamaster that another watchmaker took apart, I did of course decline. I don’t like to mop up other people’s mess, and think that whoever takes a watch apart, should put it back together again.

In this case, though, the watchmaker couldn’t put it back together, as he was late. So stupidly, I agree … Continue reading
