Sugess MoonPhase Master S437-2

Sugess MoonPhase Master S437-2 – Automatic Watch with Genuine Moon Phase & Big Date

The Sugess MoonPhase Master S437-2 combines classic watchmaking with a sophisticated mechanical complication. At its heart is a genuine moon phase display, complemented by a distinctive big date display and powered by the automatic Seagull ST2528 movement.

With a diameter of 41 mm, the MoonPhase Master offers an elegant yet distinctive presence on the wrist. The finely detailed dial with classic leaf hands, applied hour markers and moon phase display gives the watch a refined, traditional character.

Genuine Moon Phase Display with 29½-Day Cycle

Unlike simple day/night indicators, the Sugess S437-2 displays the actual lunar cycle. A specially designed 59-tooth gear enables the watch to represent the approximately 29½-day moon phase cycle.

The big date display creates an interesting contrast to the classic design while offering excellent readability.

Seagull ST2528 Automatic Movement

Inside the watch is the automatic Seagull ST2528 movement with 25 jewels and a frequency of 21,600 vibrations per hour (3 Hz). It offers a power reserve of up to 48 hours.

The exhibition case back provides a view of the mechanical movement. Perlage, engravings and decorative finishing make the movement an attractive visual feature in its own right.

High-Quality Materials

The 41 mm case is made from 316L stainless steel and fitted with scratch-resistant sapphire crystal. With a case thickness of 13 mm, the watch maintains well-balanced proportions despite its mechanical complications.

The MoonPhase Master comes with two genuine leather straps in black and brown, allowing you to easily change the look of the watch to suit different outfits and occasions. A folding clasp is also included. The watch is water-resistant to 5 ATM / 50 metres.
