The first glimpse through the sapphire crytsal case back suggests it to be an automatic watch without chronograph, as the movement is the automatic calibre ETA 2892-A2

As well as the obvious twin disc Big Date aperture @12 if you look closely there is another smaller window between 4 and 5 for a Month indication.  The watch model is what is called a One-Year-or “Annual” Calendar and is adjusted just once per year on the 28th or 29th February. 

The dial is silver-coated with Clous de Paris guilloche in German silver, rhodinated applied indexes and the 6 flame-blued steel hands set gives excellent readability under a Sapphire Crystal.

The case is in 316 Stainless Steel with a nicely molded case crown protection swell (the crown is very well defined with a strong milled edge). 

Water Resistance is 5 bar and the case diameter is just 38.2mm and at only 12.8mm depth is quite neat for an automatic Chronograph.  A high quality leather strap with signed Nivrel buckle completes the ensemble.

Overall this is a very neat and compact model and with it’s satin finish certainly does look the part. 

Additionally, the short lugs arrangement allows this model to fit almost any size wrist.
