The case is made of white zirconium oxide ceramic with a ceratanium bezel and back, rated to withstand temperature fluctuations from 100 to -100°C (212 to -238°F). In fact, the entire piece was shaken to 10 grams at Vast’s Long Beach facility, which is beyond the strength the astronauts experienced during ascent, and they came out the other side doing just fine. Price is still up in the air.
Watch brands love to find more areas in which they can be reinvented, and the subtle “snap” of chronograph stop/start/reset buttons is the latest little battleground where R&D teams are taking the fight. Last year, Audemars Piguet took the feel of an iPhone button as its inspiration Royal Oak Rd No. 5; Now Tag Heuer She has her own point of view On ergonomics press a button.
Typically, chronograph pushers involve a combination of levers, springs and cams that are held in place with varying degrees of precision. TAG Heuer has introduced most of that with the TH80-00 caliber, after five years of development between the TAG Heuer LAB innovation department and movement maker Vaucher Manufacture Fleurier. It replaces the traditional structure with two flexible bistable components — shape-shifting parts that stabilize between positions — produced via high-precision LIGA manufacturing, a precision manufacturing technique that involves lithography, electroforming, and molding.
The result? Sharper playback that does not degrade critically. According to TAG, the 10,000th press appears identical to the first. Paired with TAG’s high-tech TH-Carbonspring oscillator (anti-magnetic, 5Hz, 70-hour reserve, COSC certified), the reworked 40mm titanium Monaco sits with the crown back on the left where Steve McQueen’s original was in 1969. You can get two versions: polished titanium with blue accents or black diamond-like carbon (DLC) with red accents. The dial is made of clear acrylic, so you can watch the matching mechanism in action.
Vacheron Constantin Overseas Lineamong the most famous examples of the “sport luxury” type prevalent in Switzerland, leans heavily on the sporty side with a full titanium treatment, GMT across four references. The color of each dial is mapped to a compass point: white for north, brown for south, green for west, and blue for east, and contrasted with the bright orange Rolex-style GMT hand for the home time zone.
The lineage goes back to a 2019 prototype built for explorer Corey Richards to wear to the summit of Everest – perhaps the most luxurious watch ever visited in such places. The 41mm case, integrated bracelet and folding clasp are all made of titanium with a matte anthracite finish on the bezel and crown. Inside is an in-house caliber 5110 DT/3, a self-winding GMT with AM/PM indicator for local time, a date pusher for local time, and a 60-hour reserve. Classic sports watch attributes, but here certified with the hallmark of Geneva, the highest official standard for fine watchmaking and hand-finishing.
