Glashütte Original Pano LunarTourbillon features

Launched in 2000, Glashütte Original’s “Pano” line has, for many collectors, come to symbolize the brand. Last year, the company gave the line a mild redesign with slightly larger cases, thinner bezels, and subtle changes to the dial.

This year, GO added a tourbillon to the collection, the Pano LunarTourbillon. The PLT (as it will certainly come to be known) has a 40 mm by 13.1 mm rose-gold case.

The dial has the same asymmetrical layout as the brand’s PanoMatic Lunar model, except that the tourbillon has replaced the seconds subdial. GO says the dial layout is in harmony with the golden ratio, often represented as 1.6180329887. We’re not mathematicians, so we’ll take the company’s word for it.

The PLT is powered by Caliber 93-02, an automatic based on Caliber 93-01. The moon-phase display is integrated into the movement and is not a module.

Visible through a sapphire display back, the movement runs at 21,600 vph in 50 jewels (including two diamonds). The balance wheel has eight regulating screws and 12 weighted screws; the balance spring has a Breguet overcoil.

An off-center gold rotor winds a mainspring that provides a 48-hour power reserve. Water resistance is 50 meters. The package is completed by a semimatte Louisiana alligator strap in black or brown with a rose-gold clasp.
