Metal bracelets and a perfect fit
Metal bracelets need to fit perfectly in order for the watch to feel comfortable. But, everybody has a different perception of a perfectly fitted metal bracelet. Some like it looser, some really tight.
That's why we decided that instead of asking you to measure your wrist and select a bracelet size prior to ordering, increasing the possibility that we misjudge what would be a good fit for you, we will ship the watch with full length bracelet on, together with the necessary tools so that you can shorten it yourself to a most comfortable length (it's piece of cake, we promise).
Online purchase unavailable

Our view on watch diameters and wrist sizes
Yes, you might have a smaller wrist. But 42mm is a modest size, although it sounds big. Unless your wrist stayed the same since you were 10 years old, you'll be just fine with rocking a 47mm watch.
Just in case you're still uncertain, take a look at our smaller models.

ALARM CHRONOGRAPH
A built-in alarm is a rare complication in a mechanical wristwatch. Rarer still is an automatic chronograph with a built-in alarm. So rare, in fact, that FORTIS’s patented F-2001 movement, which went into serial production in 1996, was the first caliber so equipped.
It was created in collaboration with the Zurich master watchmaker Paul Gerber, who gave the basic caliber a single mainspring barrel and a striking mechanism with beaten mainspring and extra-large hammer. The alarm watch can be switched off or interrupted at will by means of a smooth-running pusher at eight o’clock. The alarm emits a 27 second long rattling sound after full winding.Complications
