Sinn’s best all around modern diver is getting an update this week in the U50 B, which welcomes a matte blue dial. The U50 has experienced a steady evolution since its introduction in 2020, often in unexpected ways, but the U50 B feels a natural extension of the core design. Thankfully, the rest of the watch remains unchanged, and this release serves as a welcome opportunity to reflect on the U50 five years later. The diver market has shown no signs of slowing down over that period, and Sinn has found a way to kind of skirt around the trends by leaning into their own DNA, something they’ve been pretty good at doing since the ‘90s.

The U series of divers has well established itself as the brand’s modern design DNA, and the U50 was the first to bring that into an everyday package. What began in relatively standard form, a matte black dial and your choice of a steel bezel, or an SDR black bezel. Since it was released in 2020, the U50 has seen a variety of executions, and even an offshoot collection in the T50 range. Sinn’s approach here has been anything but predictable, and the additional U50 variations we’ve seen have been more out of left field than of the standard new dial colors. But that’s exactly what the U50 B is and it’s honestly pretty refreshing as a result.

The U50 B uses a slightly desaturated blue, almost denim in appearance. It should come as no surprise that it works pretty well with the rest of the design, as this color usually does when the underlying design is sound. The effect can be dialed up with the addition of a rubber strap of the same color. The Sinn rubber strap is also worth pausing to appreciate, as its form fits to the case between the lugs, as well as the wrist, and uses a deployant clasp of the same material as the case. Of course, this is famously a watch that goes pretty well with all manner of strap choice.

The only real complaint here is the date disc, which has not been color matched to the dial, but rather remains black with white printing. It’s a small detail, but one that might get under your skin once you notice. If they weren’t ready to take the step of matching the date disc to the dial, I think a dateless option would have been preferable.

On the inside of the 41mm case, we find the familiar Sellita SW 300-1 at work, with the crown set at four o’clock along the case. It’s a wonderful package on the wrist that wears closer to 40mm in size thanks to the crown placement. It appears that this rendition is only being offered with a steel bezel, which remains captive in nature (so in theory it can be swapped with the SDR). The whole thing still boasts a 500 meter depth rating even though it’s still just a hair over 11mm thick. It’s still the ultimate everyday diver if you ask me, and I’m glad that Sinn isn’t afraid to take their time with updates such as this one.
The Sinn U50 B is available now for the price of $3,240. Sinn
