Description

The Breitling Premier Datora is Breitling’s take on a calendar chronograph with moon-phase. Featuring rectangular chronograph pushers and Arabic numerals, the heritage-revived Premier Datora displays a variety of details such as grooves on the case-sides, open sapphire casebacks and syringe hands. The Datora comes in stainless steel with a copper dial or in 18k red gold with a silver dial. “Datora” was a term used by Breitling in the 1940s and refers to a complete calendar chronograph displaying day, date, month and moonphase.

The stainless steel case measures 42mm in diameter and 15.3mm in thickness. It wears on the larger side for a classic style, coming in at 50mm lug-to-lug.

The thickness of the watch is expected of an automatic chronograph movement with calendar module. That said, the heft may take some warming up to if one was expecting a classic design.

An open caseback reveals the automatic movement powering the Datora. The Breitling Datora runs on the B25 caliber, a COSC-certified chronograph that beats at 28,800 vph and has approximately 48 hours of power reserve.

The movement is based on a Concepto C2000 movement, a derivative of the Valjoux 7750, designed by Concepto Watch Factory as an efficient ebauche for modular complications. The B25 uses a vertical clutch layout with column wheel, instead of the lesser regarded lever based movements.

Finishing is modest on the movement, with machined Geneva stripes and bevelled bridges.
