Behrens teams up with Vianney Halter for the bold, electric meter-inspired KHW Watch, in white or rose gold. The extremely dense movement combines the brand’s chain-driven hour display with rotating minute and power reserve cylinders, and a surprise on the back. It also represents a new frontier for the Chinese brand, as its most expensive offering yet.

Initial Thoughts

While Behrens’ watches do not always appeal to me aesthetically, I think the brand is an ideal champion for Chinese watchmaking. Unlike some brands marketing Chinese-built watches to global enthusiasts, Behrens is Chinese owned and operated. The brand’s founder, Lin Bingqiang, cut his teeth making parts and custom modules in Shenzhen for brands down in Hong Kong before starting Behrens in 2012.

An exploded view of the 870 part movement.

Many Chinese manufacturers excel at the engineering and manufacturing side, but have weak soft skills and lack vision. Behrens is strong on all fronts, and this is the brand’s most ambitious, and expensive, project yet. The brand may be over-reliant on computer-generated imagery, but I can confirm these watches are real, functional, and doing the rounds at Geneva Watch Week.

Case

On the heels of a collaboration with Konstantin Chaykin, Vianney Halter’s partnership is now with Behrens. This comes only days after Mr Halter’s collaboration with Massena Lab. His style dominated the aesthetics of that watch, though here it feels like Behrens took the lead.

A vintage electrical meter in Vianney Halter’s workshop first impelled the design, though the end result looks somewhat like Behrens’ “wat board” style watches.

The bezel-less sapphire crystal – nearly as tall as the mid-case – and rounded-rectangle silhouette capture the electrical meter aesthetic well, though it also resembles a smart watch, by coincidence. Despite the unusual case design, which includes a pair of buttons at 12 0’clock, the watch is still water resistant to 30 m.

This is only Behrens’ second precious metal watch, following the Kung Fu Platinum Edition from a few years back. Until now, the brand limited itself to less expensive materials, such as base metals, sapphire, and composites. Gold is appropriate for the brand’s most expensive watch, and added heft differentiates it from the similarly shaped Ultra-Light 20G.

Serpentine Hours

Inspired by the classic video game Snake, the chain running the movement perimeter completes one circuit in twelve hours with a single lumen dot acting as an hour hand. A string of six smaller dots, the Snake, chases the hour dot around and around.

The chain runs on ruby bearings, reminiscent of the Romain Gauthier’s Logical One, to minimise friction against the steel sprockets. Naturally, this chain comprises a majority of the movement’s 870 parts.

Behrens also mentions a temperature compensation system to “ensuring the stability of the micro-chain mechanism in all environments”.

While not explicitly identified, I notice the lower two sprockets are part of their own subassembly, mounted on springs. If the chain were to contract under extremely cold conditions it would compress those springs slightly, moving the lower sprockets upward, though that is only speculation on my part.

Two rotating cylinders, inspired by the aluminum disks on vintage electricity meters, flank the balance bridge. The right tracks the minutes, with one minute resolution thanks to the interaction of stationary and moving scales.

The tangled wire inspired bridges for the power train are another electric meter allusion. Despite their complexity, I suspect there are cut on a normal three-axis CNC mill with a lot of patience and care. These renders represent the movement decoration fairly: somewhat industrial but thorough and well executed.

The cylinder on the left is split between the day night indicator, and power reserve indicator. When fully wound the watch will run for three days, thanks to a pair of stacked mainspring barrels.

The balance is free-sprung, which has become very common in Chinese tourbillons over the last few years, but remains rare in non-revolving escapements.

This specific cam-style was likely inspired by the Swatch Group design used in the Powermatic 80 and others, which is adjusted using just a normal screwdriver and a tool shaped like a tiny foot to support the balance.

Flip the watch over and you’ll be greeted by the date and moon phases on the case back. Double sided pocket watches are an elegant way to present lots of information without crowding a single dial, but it is often awkward in wristwatches without an easy way to reverse the case while on the wrist.

A case back moon phase display works well enough as it’s not very useful in everyday life, though the date might benefit from front facing placement. Both are adjusted using a pair of buttons in the case band.
