A silver dial on black leather is about as classic as watches get, and the Mido Commander Chronometer M021.431.16.031.00 adds a credential most classics lack: COSC chronometer certification, verified accuracy of between minus 4 and plus 6 seconds a day. That performance comes from Mido's Caliber 80 Si, a self-winding movement with a silicon balance spring and up to 80 hours of power reserve. You can watch it through the transparent caseback, and on the dial it drives a day-and-date display at 3 o'clock.
Hands and indexes are coated with Super-LumiNova for evening readability. The Commander collection dates to 1959 and remains one of Mido's pillars, its rounded case shaped as a tribute to the Eiffel Tower. In this 40mm, 11.3mm-thick format it wears beautifully under a shirt cuff, and the black leather strap makes it a natural partner for suits and dress shoes.
