American watchmaker RGM has added a world timer bezel to its Model 500 GMT watch.
The sporty watches have an internal 24 hour bezel, with a central GMT hand circling once in a day while the hour hand goes around every 12 hours.
Its external bezel has 24 world cities in different time zones deeply engraved with their type filled with ceramic.
The bi-directional bezel is designed for quick adjustments and has RGM’s in-house made and designed click system.

To help ensure durability, the watch has two case-back gaskets, a 2mm thick sapphire crystal, and a high-quality screw-down crown.
The watch is driven by an RGM-customized ETA 2893-2 automatic movement with Cote de Geneve and perlage finishing.
There is a choice of a flat black or sunray blue dial for the 41mm steel watch, which sits 11.3mm high on the wrist.
It can be bought on a leather or rubber strap for $4,450. There is also the option of a five row steel bracelet with alternating polished and brushed links.
