In-Depth: The A. Lange & S?hne 1815 Chronograph, Revisited
One of the more interesting comparisons we’ve done in recent months was in the latest edition of Three On Three, in which we compared three really strong watches – all hand-wound, all chronographs, and all with in-house movements. As we noted then, in-house hand-wound chronograph movements in wristwatches have actually been something of a rarity in European watchmaking; chronographs are surprisingly challenging to engineer (I remember Cartier’s Carole Forestier once telling me that a tourbillon was actually much easier to do than a good chronograph movement) and in general, if you wanted to do a chronograph wristwatch you’d get a movement from a specialist supplier like Nouvelle Lemania. One of the biggest surprises to many watch enthusiasts, therefore, was the introduction by A. Lange & Söhne, in 1999, of the Datograph, which instantly became one of the most talked about watches in the world, and which was not only an in-house chronograph, but an in-ho

Solid 5 year interval
Hi all, can anyone let me know their experience with service intervals for their AP. I understand when you purchase new, you can send the watch in for a pressure test after 2 years and then you receive an extension. My question is specifically for after that. Can you get a solid 5 years between servicing or are these best serviced every 3 years. Thinking of a 15400 but would like to know the answer to this one.Thanks everyone.

is this tritium or radium?
I had always thought that my Omega cal 600 had tritium lume on the dial considering the fact that it was produced in 1960, however i have never been totally sure.

Omega OP: Should it be the next one.
I could use some opinions on my next purchase. I have been looking at the Omega OP (see image below) as my next purchase. I've never had one and never worn/tried one on. The orange has somehow placed me in a trance and I can't get away from the over-all appearance. I'm not wanting a daily wear time piece b/c i already have one love but I am looking to add an additional option for those rainy days. I could really use some good hard opinions from those who actually know about the watch. I plan on putting one on in the next few days from a local AD.
