GMT 24H SAPPHIRE BEZEL
TRACK 3 TIME ZONES
Bi-directional 24-hour graduated bezel made of scratch-resistant sapphire crystal, offering a high-quality appearance. Designed for travellers, the GMT complication makes it possible to read up to 3 different time zones thanks to the GMT hand and the rotating (24 clicks) bezel.
DAY / NIGHT REFERENCE
During the Antarctic summer the sun is almost constantly in the sky, the days lengthen rapidly until the sun no longer sets, a phenomenon called the Midnight Sun.
During this perpetual day time, the 24-hour graduated GMT bezel makes it possible to distinguish day from night. The bezel is divided into two halves each with a distinct color, one corresponds to the daytime hours, the other to the night-time hours.
SUPER-LUMINOVA GRADE A
The markers, hands and bezel are treated with Super-LumiNova Grade A to ensure increased readability. The bezel’s luminescent marker at 12 o’clock and the luminescent arrow-shaped minute hand provide scuba divers with an accurate indication of dive times in poor visibility conditions at the greatest depths. The luminescent 24-hour scale on the bezel and the luminescent hands facilitate reading of the three time zones in all situations.
NAVIGATION INSTRUMENT
Primarily a time-measuring instrument for professionals and explorers called upon to travel the world, the Superman 500 GMT can also prove useful as a backup for navigational instruments.
To locate the cardinal points in the southern hemisphere, simply point the 12 o'clock index on the watch dial towards the sun, the north/south line is halfway between the 12 o'clock index and the hour hand.
