Patek Philippe Nautilus 3800J Beyer
Compared to the current prices of Nautilus pieces on the grey market, the ref. 3800 seems like an absolute bargain to me. Directly descendant to the 3700 and with an immense range of dial configurations, one can very easily amass a few of them if they get carried away (case and point with me). Double signed and special dials will always be the most appealing, the double signature bringing a beautiful balance to the dial very similarly to the way the AP at 6 o’clock on the 5402 does. The premium on double signed pieces for 3800 are still quite soft and are much more important and interesting on a collector’s view than a regular old 5711. My tip for double signatures is to learn about the retailer and find one you are particularly drawn to rather than just go for the Tiffany due to hype.
