Sporty Meets Dressy: The Baume & Mercier Formula 5 is a classic 1990s sport chronograph, and although it doesn't pop up very often on the used watch market, it has a lot to offer in terms of style and robustness. With the Formula 5, you get a powerhouse Swiss made caliber 7750 automatic chronograph movement, swivel lugs (for ultimate comfort). The strap is not an original Baume & Mercier, but it is an authentic leather strap. Reference: MVO4F013 Movement: Automatic, Swiss made Caliber: ETA/Valjoux 7750 Case: Stainless steel Diameter: 40mm Thickness: -13mm Strap size: 20 mm Lug-to-Lug: -45mm Dial: Black with day/date at 3:00 Band: Black leather strap Condition: Very good overall. The chronograph starts, stops and resets as it should. The date flips when it should. The crystal has multiple scratches and blemishes but it is not chipped. The bezel is very nice with the tachymeter scale. THE WATCH HAS BEEN REVISED, DECEMBER 2023.
