A very elegant watch especially with the raised Breguet numerals but I have noticed one thing. Perpetual calendars like the 3940,5140 and 5940 are not so legible when wearing them. Yes one can tell the time at first glance but it is more challenging to view the information on the sub dials. Perpetual calendars that show the day and month on a separate window in arabic numerals like the 5059,5159, 3970,5970,5270,5004,5204 are a lot more legible. This is the main reason why the 5940G, as beautiful as it is, has remained in my collection for only two years., The fact that I needed to finance a dream watch was an additional factor why it was the first to leave my collection.
