The Dutch independent brand donates a watch with a constant force mechanism and a frosted dial for the charity auction, held in Geneva on November 9.
Grönefeld 1941 Remontoire for Only Watch 2019
The sculpted polished stainless-steel case measuring 39.5mm in diameter is executed with a specially shaped cutter to create its characteristic hollowed, concave recesses and convex surfaces. The one-off solid silver dial features a subtly smoke-colored frosted surface with highly polished hour markers, and a pretty minimalistic layout with blued hour and minute hands, small seconds, and the remontoire mechanism, partially visible at 9 o’clock. The latter is obviously one of the G-05 manually wound movement highlights. The eight seconds Remontoire mechanism delivers a constant force to the escapement thus leading to better isochronism and precision.

In terms of finishing the Grönefeld brothers are usually second to none, and this particular 1941 Remontoire is no exception. The stainless-steel bridges are hand-beveled, with the centers delivering a sublime contrast thanks to their micro-blasting. Various element-decorations go all the way from snailed and grained to spotted and frosted surfaces. The movement includes a balance wheel equipped with a free-sprung over-coil hairspring with triangular stud. There is also an Only Watch engraving. The watch comes on an ostrich leather strap with orange lining and a stainless-steel pin buckle. The estimate is CHF 48,000 - 69,000.
