About this reference
The Grand Seiko SBGM245 is a 40.5 mm steel Sport GMT with a blue sunburst dial, steel bracelet, sapphire crystal, and 200-metre water resistance. Its date and second time-zone display are framed by a compact case that feels ready for travel without the bulk of the larger Sport references. LumiBrite and a solid case back reinforce the watch's direct, functional character.
Calibre 9S66 is an automatic GMT movement with a central rotor, bidirectional winding, and hand-winding capability. One barrel supplies 72 hours of reserve, while 35 jewels, a free-sprung balance, and MEMS escapement components support the 28,800 vph architecture. Hacking seconds, six-position testing, and a stated +5/-3 seconds per day complete a measured mechanical traveller built around everyday usability.
