COLOSSEUM III – KRONSEGLER modular caliber on ETA base movement

The COLOSSEUM series consists of the sold-out limited edition models COLOSSEUM from 2010 and COLOSSEUM II from 2015 and was completed in 2019 with the COLOSSEUM III.

The KRONSEGLER CALIBER 26 is a newly developed modular construction on a Swiss-made base movement with automatic winding on 23 rubies. The power reserve of the CALIBER 26 is 40 – 46 hrs after full winding, and the oscillation rate is 21,600 A/h.

COLOSSEUM III is the continuation of the limited series COLOSSEUM II. The simple classic dial in antique white is set with blue or red large Roman numerals and scale details. A Rehaut is placed on the edge. In the lower third of the dial is the Latin saying: Tempus Rerum Imperator [Time is the ruler of all things].

The COLOSSEUM III watch series uses a proven 3-piece KRONSEGLER stainless steel case, which features a shimmering round case and a flat, stepped bezel. Depending on the model, the watch has a two-layer genuine gold-plated and satin or rhodium-plated polished finish. The curved COLOSSEUM lettering is engraved on the left side rim. The case glass is slightly curved, which creates an exclusive shine on the front view of the watch. In addition, the glass is reinforced with a scratch-resistant diamond film. The central hands are cut minimally thin in the center and open diamond-shaped at the ends.

The COLOSSEUM III is limited to 300 pieces. The watch back is engraved with the serial number of the watch and has a central glass viewing window. The rotor of the movement is golden and decorated with ornaments. The padded leather strap has an alligator embossing and crest-decorated gold-plated or rhodium-plated safety folding clasp, and there is also another small KRONSEGLER crest on the front visible area of the strap.

The watch is delivered in the Kronsegler exclusive box with a detailed brochure with operating instructions and instructions for use as well as a numbered certificate magnetic card.
