Angelus Chronodato full calendar chronograph in stainless steel
The Chronodato model was introduced by Swiss watchmaking power house Angelus in 1942. This was the world’s first chronograph with a full calendar (day-date and month) and due to these features, it became highly popular among consumers. So much so, in fact, that the line was in production for roughly 10 years. In the 1950’s, however, the Chronodato model was replaced by the amazing Chrono-DatoLuxe family, which lacked the month display but had a moon-phase and a big date instead. It was produced in stainless steel, gold plated and solid gold versions with different dial variations.
It is a rather large watch at approx. 38 millimeters and thick too, close to 13mm. Not a flat watch by any means but still sits comfortably on the wrist and does not stick out too much even with the high crystal these watches usually/should come with. Below you can see the various case types the Chronodato was sold with, pay attention to the little photos showing the different lug variations available at the time.
Now what’s really important to see is that this watch is a so-called “manufacture” meaning that the company did not use a movement from another brand but did everything (development, assembly) in-house. The movement is the Angelus caliber SF 217, which is based on the SF 215 that I already featured in my aforementioned article about the Angelus L.E. Interestingly enough, the SF 215 is the same movement Panerai used in their Mare Nostrum chronograph so technically the basis of the Angelus Chronodato is the same as one of the first Panerai chronographs. The SF 217 is a 17 Jewel hand wound column-wheel movement with triple calendar and chronograph features.
