Two brothers cut from the same Manueel One family, but each with its own distinctive identity: one immensely technical and scholarly looking, with the other hopelessly romantic and warm at heart. The final iteration of Manueel One, available 8 May.
Each features a patterned tremblage centre surrounded by a two-step brushed surround diamond-cut at every edge. Highly polished diamond-cut batons that serve as hour markers are individually hand-applied with an overhang at the tip that optically floats above the tremblage centre - providing incredible depth and dimensionality to the dial. The applied metallic GRØNE logo has a 3-dimensional effect. The words "Oldenzaal”, ”Manueel" and “Netherlands” are precision printed on the dial.
The dial is then covered with a scratch-resistant sapphire crystal that has an anti-reflective coating on both sides. The watch features a finished and decorated Swiss-made manual winding caliber that has been torque-adjusted to a ‘just right’ crown-winding feel that the brothers prefer. A hacking seconds mechanism is also featured on the watch.
the DIAL
New to Tim's and Bart's One is an additional step of fine circular graining applied to the patterned tremblage at the centre, surrounded by a two-step circular brushed dial with a diamond-cut at every edge. Highly polished diamond-cut batons that serve as hour markers are individually hand-applied with an overhang at the tip that optically floats above the centre - providing incredible depth and dimensionality to the dial.
The applied metallic GRØNE logo has a 3-dimensional effect. The words "Oldenzaal”, ”Manueel" and “Netherlands” are precision printed on the dial.
the CASE
The Manueel One's 38.5mm case takes inspiration from the Grönefeld 1941 case first introduced in the award-winning Remontoire and Principia series.
“An evolution of the 1941 case design, the bezel of the Manueel One has dome surfaces between the lugs, but concave on the side of the case. The crown is typical to our brand. It is very conical, which makes it more comfortable while winding. On the side, it has the GRØNE brothers logo, which signifies us, the two brothers.”
Measuring 38.5mm and a very restrained height of 9mm (excl sapphire), it is milled in stainless steel and is polished to a very high degree.
the MOVEMENT
"For GRØNE's timepieces, we have chosen a manual movement. We want the customer to be engaged with its mechanics. Each morning, the owner will be reminded of the intricate manual movement within."
The GRØNE Tim & Bart's One leverages a decorated Swiss-made manual winding caliber SW210 that has been torque-adjusted to a ‘just right’ crown-winding feel that the brothers prefer.
The movement has a power reserve of 42 hours and is water-resistant to 5 atmostpheres.
back to OLDENZAAL
An engraved solid caseback is that of an ancient map of Oldenzaal from 1626, with the Grönefeld logo marking the current location of the brothers' atelier. The miniaturisation, in high-definition of an old map onto metal was incredibly hard to do, and had to be redrawn line-by-line. to achieve the desired effect the brothers wanted.
It is a reminder of their beginnings and pays tribute to their heritage as the third generation of watchmakers, continuing a legacy that began with their grandfather and spans over a century of watchmaking. It allows collectors to carry a piece of Oldenzaal with them.
