Glashütte Original has launched two new flyback chronographs that draw from opposite ends of its own history. The Glashütte Original Senator Chronograph takes its cues from precision observation pocket watches made in Glashütte during the late 19th century. Its sibling, the Senator Chronograph Navigator, looks to the brand's 1940s pilot instruments — specifically the UROFA Calibre 59, which Glashütte describes as the first modern wristwatch flyback chronograph built in the town. Both are available now from $16,100 on leather or synthetic strap, or $17,100 on a steel bracelet.

The Case: 41mm, Slimmer Than You'd Expect
Both Glashütte Original Senator Chronograph models share a 41mm stainless-steel case measuring just 12.9mm thick — a genuinely compact profile for a flyback chronograph with a Panorama Date. The lug-to-lug runs to 48.5mm. Sapphire crystals front and back, anti-reflective on both sides. Water resistance is 50m. Mushroom-style pushers sit at 2 and 4 o'clock with a tachymeter scale on the rehaut; the Navigator's onion-shaped crown and larger pusher profiles tip the design further toward its pilot watch references.

The Two Dials: How Each Glashütte Original Senator Chronograph Reads
The Senator Chronograph wears a galvanic silver dial with a fine grainé texture, blue-coated solid-gold Roman numerals, and blued hands — formal, restrained, and clearly descended from maritime observation watches. The 30-minute counter and small seconds face each other across the dial; the Panorama Date sits at 6 o'clock within a white-gold frame.

The Navigator takes the same layout and rewrites it for legibility: matte black dial, luminous Arabic numerals, white-lacquered chronograph and small-seconds hands. The Panorama Date adopts a clean sans-serif typeface versus the serif font on the silver model — a detail that accurately signals each watch's intent before you clock any other difference.
Calibre 37-24: The New Movement Inside Both
Both watches run the newly developed Calibre 37-24 — an integrated automatic column-wheel flyback chronograph. Its diameter is 34.2mm and height just 8mm, which is how the overall case keeps to 12.9mm despite the complications on board. The movement beats at 28,800vph with a 70-hour power reserve, a silicon balance spring for magnetic resistance, solid-gold regulating screws, and Glashütte Original's swan-neck fine adjustment. The 95% in-house component ratio reflects serious manufacture depth.

Through the sapphire caseback, the Calibre 37-24 shows its three-quarter plate with Glashütte striping — a finish that Glashütte Original notes requires three passes at 1/100mm depth each, compared to a single pass for conventional Côtes de Genève. Bevelled steel components, blued screws, and a newly developed skeletonized 21-carat gold rotor complete the display.
Straps and Availability
Each Glashütte Original Senator Chronograph ships with a quick-change strap system and a choice of blue or black Louisiana alligator leather, a sand-coloured synthetic strap, or a stainless-steel bracelet. The folding clasp itself now uses a new quick-change mechanism, allowing it to transfer between straps without tools — a practical update that the previous generation lacked. Pricing: $16,100 on leather or synthetic; $17,100 on bracelet. Available now at Glashütte Original boutiques and authorised retailers worldwide.
