Quick TakeLet's talk about this blue beauty. Forget fussing with dates – the annual calendar on this Master Collection (powered by the smooth L897 automatic) handles month and date changes like a champ, needing just one tweak a year. That sunray blue dial? Pure class under scratch-proof sapphire. It's got presence at 42mm but wears nicely, and the 72-hour power reserve means you can set it down for the weekend. Finished with a proper blue alligator strap, it’s a seriously smart piece that doesn't shout, it just performs.

DescriptionThe instrument case is constructed from stainless steel in a round configuration, measuring 42.00 mm in diameter and 10.80 mm in thickness. Lug-to-lug distance is specified at 49.70 mm, with an inter-lug width of 21 mm. Protection for the dial is provided by a scratch-resistant sapphire crystal. The case back incorporates a transparent sapphire crystal window, permitting observation of the internal mechanism. Overall weight is recorded as 87.8 g. The design ensures water resistance up to 3 bar.

Internal operation is governed by the Caliber L897, a self-winding mechanical movement operating at a frequency of 25'200 vibrations per hour. This movement provides a power reserve extending up to 72 hours. Functionality includes the display of hours, minutes, seconds, and an annual calendar complication indicating both month and date. Visual interface comprises a sunray blue dial featuring applied indexes as hour markers. Time indication is achieved via silvered polished hands. The watch is affixed to the wrist by a blue alligator strap, secured with a triple safety folding clasp incorporating a push-piece opening mechanism.
