Certina DS-2 Automatic Calibre 25.651 – Service

I have been meaning to feature a Certina DS-2 for a while on the blog. Having a penchant for vintage divers watches, the iconic “turtle back” originating from the late 1960s is certainly worthy of a feature, with its substantial look and novel design. It is powered by an in-house automatic Certina Calibre 25.651. One of the particularities of the DS-2 range is the floating movement design, where a rubber ring is sandwiched between the case and the movement, to absorb energy in case of a shock.

Longines Calibre 12.68Z model 7033-4 – Service and restoration

Nick sent me this vintage Longines watch for a service and restoration. I have already featured an almost identical watch on the blog in this article. The service on that particular watch had been perfectly straightforward, but in the case of Nick’s watch it turned out to be a little more complicated as you are about to find out….

Elgin 16S Grade 312 Pocket Watch – Service

My good friend David gave me this Elgin 16S Grade 312 Pocket Watch for a service and a bit of TLC. It was manufactured by Elgin which was an American company based in Illinois. I was able to date the production to 1921 from the serial number. This would have been a very good quality watch (and expensive at the time). The case is 9 carat solid gold.

Waltham Chronograph Valjoux 7733 – Service

On the blog today is a vintage Chronograph by American watch company Waltham. It is powered by a Valjoux 7733. “Valjoux” was a manufacturer named after the “Vallee du Joux” in Switzerland, primarily known for its Ebauche Chronograph movements, and widely used by many manufacturers in the 1970’s. The Valjoux 7733 is a cam type Chronograph (as opposed to Column wheel type), with a horizontal clutch mechanism. It was produced in very large numbers, and over the years has earned itself a well deserved reputation for reliability and robustness.

Cyma Navystar Cymaflex R.459 – Service & Repair

Silas sent me this rather lovely Cyma Navystar watch for a service. He reported very poor timekeeping (about  20min/day fast) and the crown did not sit flush against the case, so the watch was definitely in need of attention.

The watch is powered by Cyma’s calibre R.459, which uses the interesting antishock device called “Cymaflex”, more on that later.

Omega Calibre 285 9ct gold watch- Service

This week under the loupe I have another very interesting vintage watch with this 9ct gold case Omega Calibre 285. The owner, David, sent me the watch for a service and a bit of TLC. The watch belonged to his late father, and was an engagement present from his mother, so needless to say it has huge sentimental value to David. The serial number dates the production of the watch to 1961.
