Behrens Ultralight 20G BHR030 Titanium, 2025 Full Set

$7,488.00

The Behrens Ultralight 20G is exactly what the name says: a fully skeletonized mechanical watch whose head weighs about 20 grams without the strap. This 2025 example, reference BHR030 from the Inventor collection, comes as a full set with box and papers.

The curved trapezoidal case measures 42.6 x 38.2mm in grade 5 titanium, with a sapphire crystal and a solid caseback. It disappears on the wrist.

Time is read through bi-retrograde hours and minutes across a skeletonized dial, with a power-reserve indicator. Powering it is the in-house Calibre BM02, a manual-wind movement at 28,800 vph with a 38-hour power reserve.

It is fitted with a white fluoroelastomer rubber strap and titanium pin buckle, and is water resistant to 30m. Condition is good pre-owned and it runs well.
