The launch report listed a retail price of EUR 39,000 at the time. That is historical pricing, not a current quote: Breguet’s current product page directs buyers to a point of sale for recommended retail pricing.
What changed in the 2020 Classique 7137?
Breguet’s 2020 update was primarily aesthetic. The collection gained a white-gold model with a blue dial, while the rose-gold version retained its silvered dial. Both received revised dial guilloché patterns and a redesigned moon-phase display. The launch report describes the two watches as sharing the same core layout and movement, with no functional difference reported between them.
Two references, two material and color combinations
| Reference | Case and dial | Strap and buckle |
|---|---|---|
| 7137BB/Y5/9VU | White gold; blue dial, described in the 2020 launch report as “Breguet blue” | Blue alligator strap; white-gold folding buckle |
| 7137BR/15/9VU | Rose gold; silvered dial | Brown alligator strap; rose-gold folding buckle |
Guilloché and moon-phase changes
The 2020 dials use three named guilloché patterns: clous de Paris in the center, panier maillé on the power-reserve display and damier on the date counter. The moon-phase display also changed: the earlier gold Man in the Moon motif gave way to a silver embossed moon with craters, shown against a starry sky.
What was the 2020 launch price?
Monochrome Watches reported a launch retail price of EUR 39,000 for the 2020 models in its article published on 17 March 2020. This figure is a historical launch price, not an indication of what either reference costs now. Breguet’s current Classique Phase de Lune 7137 product page lists several references and asks prospective buyers to contact a point of sale for recommended retail pricing; it does not state a current price.

Case, movement and specification differences between sources
The 2020 launch report gives the models a 39 mm case, 8.65 mm thickness and automatic calibre 502.3 DR.1. It reports 256 components, 35 jewels, a frequency of 3 Hz and a 45-hour power reserve. It also lists a 3.65 mm movement thickness, a silicon balance spring and water resistance of 30 m.
Breguet’s current official product page identifies calibre 502.3 DR1 and lists a 39 mm diameter, 8.7 mm case thickness, 256 components, 3 Hz frequency, 46-hour power reserve, 3.6 mm movement thickness and 3 BAR water resistance. These are source-specific figures, not a single reconciled specification: the official page and the 2020 report differ on power reserve, case thickness and movement thickness. Breguet states water resistance in BAR, while the launch report uses metres.
