Antiquorum Offers Important Rolex GMT-Master with Bathyscaph Trieste Connection
On Wednesday evening December 8, Antiquorum will offer 365 modern and vintage timepieces at its Manhattan headquarters, including a historically significant Rolex GMT-Master that belonged to Lt. Don Walsh who, along with Jacques Piccard, piloted the bathyscaphe Trieste to the deepest point in the world’s oceans. This important Rolex GMT-Master, ref. 6542, belonged to U.S. Navy Lieutenant Don Walsh, the Officer-in-Charge of the Navy’s Bathyscaph Trieste. Lieutenant Walsh and Jacques Piccard piloted the Bathyscaph Trieste to the deepest place in the world’s oceans: the Challenger Deep in the Marianas Trench, 200 miles southwest of Guam. The Trieste descended to a depth of 35,800 feet. Subsequent to the dive, in April 1960, Rolex gifted Lieutenant Walsh a Rolex GMT- Master. Also in recognition of his achievement, Lieutenant Walsh was awarded the Legion of Merit, the Navy’s second highest non-combat medal, by President Eisenhower at a ceremony held at The White Hous

Rebellion 540 Magnum Tourbillon Watch: Pedal-To-The-Metal Horology
When it comes to cars and watches, there's a definite link. For some brands (be it car or watch) that linkage can be a bit more tenuous, and may consist of a logo swap. For the folks over at Rebellion?though, they're taking it to a whole different level. For starters, they've actually got a racing team - one that raced in the Le Mans Series Championship (2011) and FIA World Endurance Trophy for Privateers (2012). This means they're used to creating high-end, precision, lightweight components for their cars. From what I can see of their latest watch, it seems their horology follows in the same footsteps.The 540 Magnum Tourbillon makes liberal use of materials commonly found in race cars: magnesium; aluminum; titanium; and carbon fiber. Surprisingly, these materials show up in the movement. The mainplate is made of aluminum, while the 3/4 back plate is made from carbon fiber. I've seen plenty of CF dials and even cases, but this is the first time I recall seeing the material used within

AC February Adjustment
I recently added my first PP, a 5726. This is also my first AC watch. First question: For AC PPs like the 5726, when do you adjust your date for February? On March 1st or on the 28th / 29th of February? The manual says not to advance the date when it's either the 30th or the 31st because the month change mechanism is in motion. To me it would make since to adjust on the last day of February and before the date change mech is in motion.Second question: Does the movement think February has 30 or 31 days? That is, would you set the date to the 30th or 31st on the last day of February? Reading through the manual I did not see where it specified this. I realize I have a while before I need to worry about this, but I was just wondering.

PAM 728 or PAM 736
So now I am debating between the blue dial Luminor Due PAM 728 and the green dial LE PAM 736. If you were me, which would you choose? They are comparable in price to where the price is not a factor. PAM 736: PAM 728:
