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.

Eterna Matic 3000 Sevenday Calibre 1457U – Service

This week I am featuring this Eterna Matic 3000 Sevenday on the blog. The watch is powered by Eterna’s Calibre 1457U, an automatic movement with a day date complication and quick set date mechanism. Eterna had a pioneering role in the development of self winding calibres, with the development in the late 1940s of the first Eterna Matic movement, using a friction-reducing ball-bearing mounted rotor system. The 145X and 146X movement family follow on from the success of the first Eterna Matic, and were known as ultra-thin automatic movements ( 3.6 mm thick, and 4.15 mm for the day date).  It is commonly known as the ancestor of the famous ETA 2892 movement, the high end Calibre by ETA found in many prestigious watches for the last few decades. It is worth noting that ETA was founded by Eterna, so it is no surprise that even the movements produced nowadays by ETA (currently owned by the Swatch Group) share some  common DNA with Eterna calibres.
