Designed to let you ease your way through time zones and appear in the boardroom after a dip in the ocean, the self-winding Z4 is a watch that minds its own business and minds it well.

Harry Winston’s ideal traveller’s watch is the fourth in the Project Zalium series, launched by Ronald Winston in 2004 as “watches of finesse and force.”

The 44mm case accommodates two separate hour-and-minute dials for your business and leisure time. The associated graphic displays of daytime and nighttime, for each time zone, reveal, at a glance, when to place calls around the globe. By pressing the repeater-style trigger on the left side of the case, you can click from one time zone to the next.

The easy-to-read date, quick-set by the crown, is framed vertically in the interplay of discs for the minute display and hour.
Completing the indicators is the tiny rotating shuriken symbol - a multi-bladed throwing weapon, a feature of all Project Z watches - which shows that the movement is functioning normally.

The sophisticated time-zone module was constructed in-house by Harry Winston on a robust, self-winding calibre.

Blue on carbon black or white on anthracite grey balance clarity and discretion on four levels of the dial.

Zalium is the hard, light, zirconium alloy of which Z watches are crafted. Developed for use in jet engines, its hypo-allergenic properties and extreme resistance to corrosion make it ideally suited for watchcases.
Its hue is a matte battleship grey with a celestial lustre and a dark, sophistcated gleam. The case has mobile lugs for comfort on the wrist, and those “in the know” will recognise Harry Winston’s emblematic motif protecting the crown.

Harry Winston is producing a limited edition of 300 Z4 watches. As an embodiment of Harry Winston’s promise to deliver “nothing but the exceptional,” this elegant and beautifully crafted watch is well-deserving of its place among the Project Z models.
