In a way this watch is an anachronism in the context of modern perpetual calendars. Perpetual calendars have evolved to an amazing extent in the last twenty years, and fully synchronized perpetual calendars, some of which can easily be set forwards or backwards without damaging the movement, have become more and more prevalent. However there is a lot to be said for this approach as well – this is a very distinguished movement, in an absolutely classic layout, from a manufacturer whose stock-in-trade is doing things the old fashioned way. And of course, the use of this movement allows for the construction of an elegantly thin perpetual calendar watch, at 8.9mm thick (for reference, the thinnest perpetual calendar ever, at least so far, is the AP RD #2, at 6.30mm thick – however this is thus far a concept rather than a production watch) Sure, it might be mid-20th century watchmaking from an engineering standpoint, but that’s not a bad thing at all in this case – after all, not for nothing do many connoisseurs think of the 1950s and early 1960s as the high water mark for watch design, and this classic design is strikingly beautiful in blue.
