**Model:** Breguet Type XX Transatlantique Reveil 3860 **Condition:** Excellent, some small hairlines here and there from general use (can easily be polished out) I purchased this NOS at an authorized Breguet dealer in Rome; September 2022. **Full kit:** Inner/Outer box, warranty booklet (filled out by AD), Breguet registration book, Original reciept **Case Size:** 39mm **Strap:** 21mm; Original Breguet alligator strap with signed deployment clasp and additional brown leather Delugs strap **L2L:** 45.7mm **Thickness:** 14.5mm **Movement:** Breguet cal 579 (non hacking), 48 hours power reserve, with alarm complication **WR:** 100m **Crystal:** Sapphire Screw down crowns and case back **History** From my research I’ve gathered there were only around 500 of these ever made. It is the cousin to the popular Breguet Type XX Chronographs (Model 3810) and utilizes the same case design.  Instead of a chronograph, this model (3860) has a unique mechanical alarm complication. This piece is in excellent condition (see pics), I've only ever worn it a hand full of times. It has spent most of its life with me stored in my watch box. The alarm complication works perfectly and I will include instructions on how to use it. You will not find another one of these in this condition. I’ve only ever seen one other one for sale and it had a broken crown. I lucked into this one brand new (NOS) when I visited the Breguet AD in Rome. **$8,750 shipped conus insured** Happy to have a Zoom call with serious buyers to discuss the piece, its history, and the complications.
