Chronometer certification is a promise of precision, and the Mido Multifort Chronometer M005.431.22.031.00 makes that promise at a refreshingly attainable level. Its movement has been independently tested by the COSC, the Swiss official chronometer testing institute, so the accuracy is verified rather than merely claimed.

That movement is Mido's Caliber 80 Si, an automatic with a silicon balance spring that resists magnetism and temperature changes better than traditional alloys. It is a fitting upgrade for the Multifort, a line that began in the 1930s as one of the first watches to be anti-magnetic, shock resistant, water resistant and self-winding. Up to 80 hours of power reserve means a weekend off the wrist will not stop it.

Visually, rose gold accents on the two-tone bracelet warm up a classic silver dial, and the 42mm case stays a manageable 10.95mm thick.
