SIHH 2010: Baume & Mercier Classima Executives XL Chronograph and Complete Calendar

Here is a sneak peak of a new 2010 release from Baume & Mercier.  The watch is fairly “loaded” when it comes to functionality – in addition to the chronograph timers, the watch provides day, date, month and moon phase functions – or what Baume & Mercier calls a “Complete Calendar” (more on this below).


You may notice this watch is called a “complete calendar” rather than the “perpetual calendar”.  I believe this is for good reason and probably indicates that, unlike higher end watches with “perpetual calendars” that can set you back $10,000-$100,000, this watch will require adjustment 5 times per year to account for the March, May, July, October and December to account for the prior month not having a full 31 days.  The red gold date hand (marking the days of the month that are marked around the edge of the dial) is a nice touch, though.

Overall, I can’t decide if I like or dislike the look of this watch, which probably means I dislike it, but I guess I’d want to see it in person to fully decide.  My preferences aside, this is probably going to be one of Baume & Mercier’s higher end pieces, and as I discussed above if you are looking for a calendar watch but don’t want to spend big bucks for a perpetual calendar this might be a pretty good alternative, depending on where it is priced. 



This traditionally and opulently finished chronograph is equipped with a high-end mechanical self-winding movement driving indications of a complete calendar (date with central pointer in 18-carat red gold, day and month through a window at 12 o’clock, moon phase at 6 o’clock) and 24h indicator at 9 o’clock. The silver-colored dial with a “grain d’orge” guilloché décor is graced with circular snailed and sun satin-finished counters. The case-back reveals an oscillating weight adorned with “Côtes de Genève”, as well as circular-grained bridges and blued steel screws. The crown proudly bears the Phi symbol.

    Curiously, this watch is not easy to find anymore. It seems a lot of people liked it.
    For me, it is a great watch for the price… if I could just get my hands in a new one.

    i love the watch but does it have a power reserve…!

    • Perpetuelle

      Power reserve is probably around 42 hours. There is no power reserve meter, but I don’t think it needs one because it is an automatic watch.
