The Panerai Luminor 1950 Left-Handed 3 Days – 47 MM (Ref. PAM00557), with its winding crown and patented crown protection device positioned at 9 0’clock on the left side of the case, recalls some of Panerai’s earliest models created for Italian naval commandos of the 1930s and 1940s. These military divers used to wear several wrist instruments at once, including compasses and depth gauges, and often preferred to wear the watch on their right wrist. The modern version of this vintage Panerai watch has a cusped caseband that distinguishes it from the traditional Luminor 1950 case and, in the historical models, represented the transition between the Radiomir and Luminor case styles. Another nod to the early Luminors is the crystal, which is made of plexiglas rather then sapphire. The 47-mm case is made of stainless steel and water-resistant to 100 meters; the black dial features Panerai’s famed “sandwich” construction of two superimposed plates enclosing a layer of Super-LumiNova; and the movement, Panerai’s in-house, manual-wind P.3000, holds a three-day power reserve in its two spring barrels. The watch comes on a natural, untreated leather strap with a brushed steel buckle inspired by the historical model’s, along with a replacement strap made of rubber.
Germany’s A. Lange & Sohne unveils its newest Grand Lange 1 watch, the Grand Lange 1 Moon Phase, which devotes prominent space on its dial for a realistically rendered and ultra-accurate moon-phase complication. The moon-phase disk, which features a patented coating process, is connected to the watch’s hour-wheel continuum, meaning it is in constant motion, just like the moon itself. According to Lange, the time that elapses between each new moon is accurate to 99.9978 percent, substantially more precise than that of most other moon-phase watches. Assuming the watch runs continuously, the display need only be corrected once every 122.6 years (though there is an easy-to-use push-piece corrector in the case flank between 7 and 8 o’clock just in case one needs to re-adjust it before then).
The solid gold lunar disk moves across a deep-blue field with more than 300 laser-cut stars of various sizes, approximating the look of a night sky. The movement, Lange’s manual-wound Caliber L095.3, is only 4.5 mm thick and stores an impressive power reserve of 72 hours in a single mainspring barrel. Like other Lange calibers, it features numerous decorative finishes as well as a three-quarter plate and bridges made of German silver. The case is 41 mm in diameter and available in yellow gold, rose gold, or platinum.
I think the ALS is the best among the three.
