First unveiled in 1996, the idea for Franck Muller’s Master Banker was birthed from the frustrations of a banker wishing to view three trading time zones at a glance. Up until that point, most timepieces displaying additional time zones only displayed the hour, not the minute hand. Inspired, Franck Muller hatched a brilliant plan to simultaneously display three different clock faces at the flip of one’s wrist – with each telling a different time. And unlike conventional 'GMT' watches, this configuration allows the user to track time zones offset from Universal Coordinated Time (UTC) by 30 or 45 minutes.

The Franck Muller Cintrée Curvex Master Banker The Hour Glass Commemorative Edition - a region-exclusive wristwatch showcasing the marque’s signature three time zone complication housed within the timeless Cintrée Curvex case. The 36.00 mm (width) x 50.40 mm (length) stainless-steel case measures in at a svelte 11.4 mm tall, and under the domed sapphire crystal features two mocha-coloured sub dials, a black sunray-finished dial, high contrast Arabic hour markers and stainless-steel feuille hands.

The 82-component self-winding calibre MVD 2800-MBSC has a bi-directional rotor, beats at 28,800 vibrations/hour, has 21 jewels, is water-resistant to 3ATM and has a power reserve of 42 hours. Replete with Côtes de Genève and sunray brushing on the bridges and rotor, circular graining on the two sides of the main plate and chamfering of the bridges. Parts have been given a 24K gold bath and rhodium plating, there's also a 24k gold finish on the written engravings and circular brushing of the rotor ball bearing. Coming on a hand-sewn brown leather strap, each Franck Muller Cintrée Curvex Master Banker The Hour Glass Commemorative Edition has an individually numbered case back and is limited to 38.
