Tim and Bart Grönefeld build watches most of us will only ever see in photographs, at prices to match. Grøne Oldenzaal is where they narrow that gap a little. It is the accessible label the brothers set up in 2024, and it has just taken on a third model, the Horologium: hand-wound, small seconds, 2,390 euros before VAT.
What you actually hand over depends on where you buy it, but either way this is the Grönefeld brothers in a bracket you can think about seriously.
Quirky, Classic and a brother each
There are two versions, called Quirky and Classic. Rather than present that as a colour choice, Grøne attaches each one to a brother and his personality. Small thing, but it gives both versions a reason to exist instead of one of them padding out the catalogue, which is more than most brands manage when they double up a reference.
They are also the first Grøne three-hand watches to get a see-through caseback, which arrives alongside what the brand describes as more refined movement finishing.
A hand-wound G100 and a raised sub-dial
Behind the display back is a hand-wound version of the La Joux-Perret G100, running at 4Hz with roughly 60 hours of reserve. The more interesting work is on the front. Centre seconds are gone, and the small seconds counter replacing them sits on a raised, diamond-cut platform carrying three finishes at once: polished, circular brushed and sandblasted. Losing the centre seconds looks like a subtraction on a spec sheet and rarely feels like one on the wrist, and three finishes on one small platform is a lot of fuss to go to at this money.
The caseband is satin-brushed against polished bezels and caseback, which Monochrome reckons makes the case read slimmer. The lugs curve downward and have been reshaped to sit across a wider range of wrists.
What the Grönefeld name is buying you here
A hand-wound dress watch under 2,500 euros with a Grönefeld attached to it does not turn up often, and Monochrome's comparison to what MB&F did with M.A.D.Editions is fair enough.
Be clear on the limits, though. The G100 is bought in rather than built in Oldenzaal, and nobody paying a fifteenth of the price of the main line should expect main line finishing. What carries across is the design thinking, and putting a display back on this one says Grøne knows precisely what it will be held up against.
A fixed selling window and 188 pieces per variant is the sort of arrangement that sells out fast. Orders open through the brand's own site on 13 August 2026, at 3pm Central European time.
