Patek Philippe Calatrava Black Dial 18k White Gold Black Leather Men's Watch 5153G-001

Girard-Perregaux 1966 Annual Calendar and Equation of Time
The La Chaux-de-Fonds Manufacture has unveiled a white gold version of the annual calendar and equation of time from its Girard-Perregaux 1966 collection. This model incorporates a useful annual calendar that takes account of the lengths of the months, save February. Also on board is an equation of time, indicating the difference between the true solar time and the mean time, or meridian time. The functions are displayed on the dial in an original yet highly readable way. As an added touch of sophistication, the calendar can be corrected by turning the crown in either direction. This makes correction easier, and the absence of a corrector on the case leaves its curves intact. The transparent caseback allows a view into the architecture imagined and executed by the watchmakers in La Chaux-de-Fonds, including the Microvar variable inertia balance.Technical specificationsCase in white goldDiameter: 40 mmHeight: 10.72 mmSapphire crystalSapphire case-backWater resistance: 30 metresGirard-Pe

Dive Watch Designs
In a world of round dive watches and Rolex Sub clones, I find this design very refreshing! Of course, I own the watch, so I should.What's your most unusual diver?

difference in straps?
I wanted to buy a standard buckle for my 24mm OEM panerai rubber strap. I was looking at the panerai price list, and noticed there are straps for 'ardillion' buckles and straps for folding buckles. if I want just a regular (non-folding) buckle, I am going to have to buy a new strap for it also? I attached a picture of the buckle I was going to bid on, but not if I have to buy another strap.
