Overview

About this reference

Moon phase at nine, 37 mm of steel, 13 mm thick: this Ballon Bleu is not a plain silver automatic, and the size is 37 mm, not 36 mm. Flinqué silver, Roman numerals, sapphire, steel bracelet with a hidden folding clasp, automatic calibre 080. Cartier no longer makes it. The current moon-phase successor is WSBB0050.

The 42.1 mm Ballon Bleu, W69012Z4, has the same thickness, a silver dial, a bracelet, and an automatic movement; Cartier no longer makes that one either. W6920100 is 33 mm with a pink dial. W6920046 is 36.6 mm silver automatic, the easy size confusion. The short code WSBB0021 is this 37 mm moon-phase watch.
