Breguet Collection: Grey Days, Spring Air

The Breguet reference 3657 is a notable example of the brand's approach to classic complications, featuring a perpetual calendar and moon phase display. This reference is part of a series that showcases Breguet's traditional watchmaking, emphasizing legibility and a balanced dial layout despite the complexity of its functions. It represents a period where Breguet continued to refine its perpetual calendar mechanisms within a more understated aesthetic.

This timepiece is housed in an 18k yellow gold case measuring 34 mm in diameter. It is equipped with the automatic caliber 502.3, which provides a power reserve of 45 hours. The watch features a sapphire crystal, contributing to its durability and clarity. Water resistance is rated at 30 meters, suitable for everyday wear. The fixed bezel frames a silver dial, which typically features Breguet numerals and hands.

For collectors, the reference 3657 appeals to those seeking a traditionally sized perpetual calendar from a historic manufacturer. Its combination of an automatic movement with a perpetual calendar and moon phase in a precious metal case makes it a significant piece within Breguet's offerings from the mid-1990s. The design adheres to Breguet's established codes, making it a recognizable and desirable example of their complicated wristwatches.
