Quick Take

Sinn, best known for its over-engineered tool watches, is the epitome of no-nonsense German design. Since the Frankfurt brand’s watches are most commonly rendered in black and white, a sunburst blue-dialed Sinn with creamy lume, like this new limited edition 103 Sa B E pilot’s chrono, attracts notice. It’s a handsome, whimsical (for Sinn) take on a familiar and proven watch.

Initial Thoughts

The 103 is one of Sinn’s more nostalgic offerings, with a lineage that traces back to company founder, Helmut Sinn’s work building watches for the German Air Force in the 1970s. It is a proven chronograph that eschews most of Sinn’s whiz-bang engineering, like moisture-absorbing capsules, hardened steel or an Argon-filled case. This is as throwback as Sinn gets – a decorated Valjoux 7750, syringe hands, familiar Arabic numeral dial and bi-directional friction bezel. Still, this watch is no slouch in the performance department – it’s both high and low pressure resistant, meaning it can survive high altitudes or deep water (to 200 meters), thanks in part to its screw-in crown and secured sapphire crystal.

The 103 Sa B E is a thick watch, as are most chronographs that run the 7750 movement, coming in at 16mm top to bottom. But with the 41mm diameter, it feels balanced. And, after all, this watch is directly descended from purpose-built Sinn pilot’s watches, which were never really meant for shirt cuff compatibility. The movement is modestly decorated and the rotor indicates the limited nature of this edition, auf Deutsch, all of which is visible through the sapphire case back.

Specs and dimensions aside, the reason I’m writing about this watch is because of how well it works in the new blue livery. The sunburst dial plays well with the ivory-colored lume on hands and markers. And anticipating the cries of, “fauxtina,” I’ll counter (as I often do) that it is simply another color in the palette and looks particularly good against the cerulean dial, adding a true warmth to this watch. The bezel is color matched to the dial, but in a matte anodized aluminum, and the color wraps around the entire bezel, which is set off well by the polished case.

The watch is available on Sinn’s H-shaped steel bracelet or on a vintage-style two-stitch leather strap, which is the way to go, in my humble opinion. Often, at Baselworld, we focus on what’s all new: the revolutionary movements, the innovative case materials, and the groundbreaking designs. But more often than not, what draws us to watches is simply how it looks on your wrist, and the Sinn 103 Sa B E is one of those watches that looks really, really good.
