Moritz Grossmann has created the limited edition Index Cocoa Rose Gold watch in collaboration with About Timepieces.
This timepiece features a 41mm, solid 3 part 18k rose gold case. All surfaces are highly polished. Made of solid silver, the dial boasts an eye-catching dark brown sunburst finish.
The hour markers have each been created by hand in solid rose gold and applied to the dial; 2 are positioned at 12 o’clock, whilst single markers can be seen at each of the other hours, decreasing slightly in size at 5 and 7 o’clock and just a single square dot at 6 o’clock, which makes way for the subsidiary seconds dial. Between each of the indices, there is a track of white printed minute markers, which have been split even further into quarter minutes with smaller indications.
Finished in the same colour as the main dial, the subsidiary seconds dial features a very tight circular guilloche. The subdial also has a white printed track around its circumference, this time indicating individual seconds, with every 5 second interval being indicated with an elongated marker.
Nestled between 10 and 2 o’clock, the Moritz Grossmann logo is also printed in white, being the only other thing breaking up the simplicity of the design.
Each of the lance-shaped hands have also been painstakingly hand crafted in-house from a single piece of solid rose gold – even the tiny, small seconds hand, which is a fraction of the size of a sewing needle.
A sapphire crystal glass has an antireflective coating on one side to prevent reflections and the extra thick, slightly cambered glass has a precision ground chamfered edge that refracts the geometry of the minute scale.
The crown is small, but perfectly formed. It features deep grooves for grip and although it does not protrude out very far from the edge of the case, the circumferential groove makes it easy to pull out the crown for time setting. The pusher for restarting the movement after setting is positioned just below the winding crown. The crown and the start button are polished rose gold.
The lugs appear long and slim, but shaped to follow the lines of the case; gently curved downwards to follow the curvature of the wrist.
Turning the piece over, there is a delight for the senses. The 2/3 plate is meticulously finished, with Glashütte stripes and chamfered edges, with the balance cock fixed above the 14.2mm balance wheel and the escape wheel cock, both being hand engraved with elaborate designs.
The winding wheels have polished bevel faces, the ratchet wheel is decorated with traditional three-band snailing and 3 raised gold chatons with pan-head screws can be seen in the centre. There are also hand engravings of the number of jewels (20), brand’s name and a small About Timepieces logo in there too.
This timepiece is powered by the manufacture Calibre 100.1. This manually wound movement has been adjusted in five positions and features 198 parts and 20 jewels, 3 of which are in screwed gold chatons.
Special features include a lateral pusher for disabling the hand-setting mode and starting the movement; a space saving and modified Glashütte stopwork with backlash and adjustment with Grossmann micrometer screw on a cantilevered balance cock. There is also a lever escapement, a separately removable clutch winder, stop seconds which is activated when the crown is pulled out (for setting) and a shock-absorbed Grossmann balance with 4 inertia.
Beating at a frequency 18,000 semi-oscillations per hour, the movement offers 42 hours power reserve once fully wound. The screw down caseback frame has a number of further engravings on it, to include Moritz Grossmann, the serial number and the limitation number. Through the exhibition case-back, the movement can be admired.
This piece is delivered on a dark brown Mississippi Alligator leather strap with matching stitching and a taupe coloured lining. A solid rose gold folding deployment clasp secures the strap.
