About this reference
With its warm ivory dial and classical GMT layout, the SBGM221 makes travel time feel at home in a 39.5 mm stainless-steel case. A box-shaped sapphire crystal, alligator-leather strap, LumiBrite, and see-through back give the dress-minded design both tactility and technical presence, while the date and second-time-zone indications stay legible.
The automatic Mechanical Caliber 9S66 supplies that functionality with a central rotor, one barrel, 35 jewels, and 72 hours of running autonomy. Its balance beats at 28,800 vibrations per hour, and MEMS-manufactured escapement components support the in-house Swiss lever architecture. The movement is adjusted in six positions to plus five to minus three seconds per day, with independent local-hour correction for travel.
