Glashütte Original Senator Chronograph Gets a Slimmer 41mm Case and a Navigator Variant for 2026

Walking past the Glashütte Original booth this week, you would have noticed something different about the new Senator Chronograph display. Two watches now occupy the space where one used to, both visibly thinner and wearing smaller than the 42mm Senator Chronograph that came before them. The Saxon manufacture has used 2026 to rebuild its integrated chronograph from the inside out, and the result is a pair of references that share an architecture but speak two different visual languages.

The classic Senator Chronograph leans into Glashütte Original’s heritage of observation-grade pocket watches from the late nineteenth and early twentieth centuries. Its silver-white galvanic dial carries a fine grainé texture, blued solid-gold Roman numerals at every position except three and nine, and blued-steel hands that tie the palette together. The new Senator Chronograph Navigator takes the same 41mm stainless-steel case and asks it to wear a black-lacquered flight-watch face, with luminous Arabic numerals carved from blocks of Super-LumiNova and sword-shaped hands that pick up light at a glance. They are two personalities built on the same platform.

A smaller, slimmer case

Both watches now measure 41mm in diameter and 12.9mm thick, down from the 42mm diameter and roughly 14.6mm thickness of the previous generation. The lugs are shorter and curved, so the watch sits closer to the wrist, and the new mushroom-style pushers at two and four o’clock give the caseband a more traditional chronograph silhouette. Polished and satin-brushed surfaces alternate across the stainless-steel body, and a sapphire crystal with double-sided anti-reflective coating sits on top, with a matching sapphire caseback exposing the movement underneath.

Water resistance drops from 100 metres to 50 metres, which is a trade-off buyers should be aware of, but reasonable given the watch’s dressier ambitions. The crown differs between the two versions. The classic Senator Chronograph uses a flat crown, while the Navigator takes an onion-shaped crown that nods to mid-century German pilot chronographs. Both carry Glashütte Original’s mirrored G logo on the cap.

Two dials, one architecture

The cleanest change is what has been removed. The previous Senator Chronograph carried a 12-hour chronograph counter at noon and a power-reserve indicator inside the small-seconds register. The 2026 version deletes both, leaving a quieter face with small seconds at nine, a thirty-minute chronograph counter at three, and the Panorama Date framed in white gold at six. The GO signature now sits where the twelve-hour counter used to live, opening up the dial and giving the central time display more breathing room. A tachymeter scale is printed on the inner flange.

The Navigator follows that same simplified layout but translates it into a pilot-watch vocabulary. The dial is matte deep-black lacquer, the recessed sub-counters carry the same vinyl-record-inspired finish, and the hands are coated in white lacquer with luminous fill. The result reads as a tool watch without ever feeling aggressive, a balance that has not always come easily to the category.

The new Calibre 37-24

Inside both watches sits the new Calibre 37-24, an evolution of the integrated column-wheel chronograph that Glashütte Original first introduced back in 2014. The architecture is still an automatic integrated chronograph with a column wheel, but the movement has been reworked to fit the slimmer case. It measures 34.20mm in diameter and 8mm thick, includes forty-seven jewels, runs at 28,800 vibrations per hour, and stores seventy hours of power reserve.

The chronograph is a flyback, so a single push of the reset pusher while the chronograph is running restarts the timing sequence. On a Navigator aimed at repeated timing operations, that flyback function is more than a convenience. It is the difference between a usable pilot’s tool and a complicated bracelet.

Regulation is handled by solid-gold screws set on the rim of the balance, with the manufacture’s signature swan-neck fine adjustment. A silicon balance spring resists magnetic fields and temperature variation, and through the caseback you can see the three-quarter plate with Glashütte stripe finishing, bevelled edges, polished steel components, and blued screws. The newly developed skeletonised rotor carries a 21-carat gold oscillation weight engraved with the mirrored G.

Straps, bracelets, and a new quick-change clasp

Each version of the new Senator Chronograph is offered with a choice of three mountings. The classic Senator Chronograph ships on a dark blue Louisiana alligator leather strap, with sand-coloured synthetic fabric or a three-link stainless-steel bracelet as alternatives. The Navigator is paired with a black Louisiana alligator strap, with the same fabric or bracelet options. All straps use spring bars at the lugs, and for the first time the folding clasp itself is part of the quick-change system, so swapping between strap and bracelet no longer requires a spring-bar tool or a trip to the boutique.

The new Senator Chronograph and Senator Chronograph Navigator are both part of the permanent collection and are available immediately through Glashütte Original boutiques and authorised retailers. On a leather or fabric strap, both versions retail for 15,900 EUR or 16,100 USD. On the stainless-steel bracelet, both retail for 16,800 EUR or 17,100 USD.
