The Senator Excellence Panorama Date Moon Phase (ref. 1-36-24-05-02-71) is Glashütte Original's symmetrical-dial flagship — a 42mm dress watch with the in-house caliber 36 manual-wind, a 100-hour power reserve, the brand's panorama big-date at six, and a moonphase aperture above. It is the reference Glashütte Original points to when the conversation turns to whether the brand belongs in the same finishing tier as A. Lange & Söhne; the cal. 36 is the answer the brand has chosen to make.

What it is

Glashütte Original introduced the Senator Excellence line in 2016 around the new caliber 36 — a hand-wind movement with twin barrels (for stable torque across the 100-hour reserve), a free-sprung balance with four gold poising weights, and a Glashütte-traceable chronometer certification administered by the brand itself that exceeds COSC tolerances on both rate and precision. The caliber 36 family added an automatic variant shortly after; the manual-wind cal. 36 in the Panorama Date Moon Phase reference is the family's purest expression. Steel and gold case options ship; the silver-dial steel reference is the canonical buy at the family's accessible end, with white-gold and rose-gold variants extending into haute-end territory.

Buying notes

Common things to check: papers and the brand's chronometer certificate (the Senator Excellence ships with a Glashütte chronometer card — verify it matches the watch's serial; a missing card is a hard ask at this price tier); moonphase disc (gold-cap painted, can chip with decades of wear in the same wrist position — verify under loupe); big-date alignment (the panorama date is a two-disc construction — both digits should sit flush at the same plane; misaligned digits indicate a date-module service issue); caliber 36 (verify the four-gold-weight balance and the free-sprung adjustment through the sapphire case-back); case-material verification (steel, white-gold, and rose-gold trade at substantially different prices — verify hallmarks on the case-back); strap (factory Glashütte Original alligator with branded buckle is the standard).

Market read

Steel Senator Excellence Panorama Date Moon Phase examples trade in the $11,000-$15,000 range through 2025-2026, against a current retail of approximately $15,800. Gold variants trade meaningfully higher (mid-twenties to low-thirties depending on metal and dial). The reference has been one of the steadier Glashütte Original positions through the 2021-2022 spike and the correction — comp depth is moderate and pricing has been stable.

Cross-shopped against the Lange Saxonia or the Patek Calatrava 5226, the Senator Excellence sits at roughly half the price for movement finishing that watchmaker reviewers cite as a credible peer.

Service expectations

Service is Glashütte Original-direct through the brand's German service center or select authorized independents in the US, UK, and Japan. Expect 4-8 month turnaround and a low-to-mid-four-figure service bill. The caliber 36 is hand-finished and the twin-barrel architecture is robust; service intervals of 5-7 years are typical.

A recent factory service with the brand's certificate is worth meaningful money on resale at this price tier.
