The Hamburg GMT DIN 8330 with display of a second time zone. On the GMT model, both the Arabic numerals of the inner 24 h scale and the arrowhead of the GMT hand are in Superluminova Dark Orange. The two logos and the date at the 4 o'clock position are recessed in a shade of gray to avoid any in-flight distractions. The screw-down stainless steel caseback, decorated with an airplane relief, ensures water resistance up to 20 ATM. A Sellita SW330 automatic movement, also in TOP quality level, ensures absolute functional reliability.
