The Class El Primero HW

The Class El Primero HW is an impressive sports version of ZENITH's classic and timeless range. It unites elegance, technical performance and a strong personality.
Although its character is resolutely mechanical - El Primero HW Class is a manual winding watch - it remains modern and contemporary: one of the most precise chronometers in the world beats at a rate of 36,000 vibrations per hour behind a dial that is endowed with a sporty and confident design. Through the sapphire back, watch lovers and aesthetes alike will have the opportunity to observe it in action.
This year, two new models have been added to the El Primero HW Class range. Both are fitted with an opaline dial and are made of steel. Choice of steel bracelet or leather strap.

Chronomaster with gold bracelet

Featuring the ZENITH El Primero 410 movement, the first integrated automatic movement, with moon phases and triple date, the Chronomaster has a well-established reputation for technical perfection.
This year, to ensure that the aesthetic of this time-keeper is worthy of the watchmaking wonders it conceals, two new models have been added to the Chronomaster range: one in 18-carat rose gold with an 18-carat rose gold bracelet, and the other in 18-carat yellow gold with an 18-carat yellow gold bracelet.
A highly structured bracelet therefore enhances the leading model of the ZENITH collection, without exaggeration or extravagance. It complements the moon phases with meticulously hand-driven gold stars, the grinded hands, the graceful applied roman numerals, and the grained, guilloché used on the rose gold model, to flatter any watch lover with practical and sophisticated luxury. Connoisseurs will surely also appreciate the finishing touches of the El Primero 410 movement, which can be admired through the sapphire glass: circular-grained bars and plates, chamfered and trued levers for the chronograph function.
