Why We Love It
What happens when a German watchmaker makes watches for a French brand using an iconic vintage Swiss design?
The Bell & Ross by Sinn Chronograph!
With only a quick glance at this cool timepiece you'd be forgiven for thinking you're looking at a vintage Heuer Reference 2446 Autavia from the 1960s. It features a 40mm steel case with block lugs, a luminous black matte dial with stylized Arabic indices, barrel pushers, a winding crown at 3:00, and a 60-minute timing bezel encircling a domed acrylic crystal - all classic Heuer hallmarks.
But with a closer look you'll see a left-justification on the subsidiary registers and a framed date window on the right - a quick indication that this isn't a hand-cranking Autavia, but rather a Valjoux 7750 powered automatic chronograph mechanism! Other differentiators include white painted luminous syringe hands, a screwback case, and two lines of text on the dial that give the game away.
Now before you go out cry foul play, its important to recognize that Sinn was once a key partner of Heuer - functioning as a supplier, casemaker, distributor, and service center for Heuer's best-known military watches, the Ref. 1550 Bundeswehr chronograph. Sinn's involvement with Heuer was deep, and one could argue they had a right to certain elements of Heuer's success.
This particular watch was produced for the French brand Bell & Ross in the early 1990s before they took off (sorry!) as the go-to marque for instrument style aviation watches. It has all the hallmarks of neo-vintage design, including an awesome creamy patina throughout, and tells an awesome story that spans nearly half a century of watchmaking history!
The Story
Sinn has been a favorite modern brand of ours for some time. Their watches are high end tools, built to exacting German standards and have classically-industrial designs. The Reference EZM 1 presented here is an excellent all around daily-beatable watch with all the elements we've come to love.
The EZM 1 has a stark, military style dial with SuperLuminova indices, red printing and a date function between 3:00 and 4:00. The case is bead blasted titanium and has a 30 bar resistance and has low temperature and pressure resistance technology.
Inside the perfectly proportioned case beats the venerable Lemania 5100 automatic chronograph movement with central 60-minute stopwatch functionality.
Fitted with a sapphire crystal and matching titanium bracelet, the EZM 1 has reached cult-like status within the watch collector community, and for good reason.
