Breitling Chronomat B13352 40 mm

The Chronomat B13352 gives the compact late-Chronomat case a stainless-steel and yellow-gold construction, measuring about 39 to 40 mm and resisting water to 100 m. Its sapphire crystal, unidirectional rider-tab bezel and screw-locked crown frame the chronograph pushers, while the two-tone Pilot bracelet extends the contrast across the wrist. The proportions remain compact even as the materials add warmth.

Breitling Calibre 13 winds automatically and uses a cam-actuated chronograph architecture based on the ETA Valjoux 7750. It runs for 42 hours and combines a date display with a beat rate of 28,800 vibrations per hour. The third-party movement can be hand-wound and hacked, and its industrial finish keeps the underlying mechanism clear and serviceable in character.
