Zenith Chronomaster T Open Concept – Ref. 95.0240.4021/77.C608
Konzeption
The Chronomaster T Open Concept represents a logical evolution of the classic El Primero range. Instead of a solid dial, an open skeletonised structure reveals the movement – a design approach that allows the mechanical complexity of the calibre to be experienced directly, without relying on decorative elements.
Caliber & Technology
The watch is powered by the El Primero 4021 automatic calibre, with a frequency of 36,000 vibrations per hour (5 Hz). This high frequency enables the measurement of tenths of a second – a unique feature that has distinguished the El Primero since its launch in 1969. The power reserve is 55 hours; the remaining time can be read via an indicator at six o’clock. A cut-out in the dial reveals the escapement. Shock protection: Incabloc. Finishing: Perlage and Côtes de Genève on the rotor.
Case & Material
Case diameter: 40 mm. Material: titanium. Thickness: 10.5 mm. Sapphire crystal on both sides; the see-through case back allows the movement’s finishing to be viewed. Water resistance: 3 ATM. Strap: textured carbon fibre strap with a triple-fold clasp in titanium.
