Stainless steel self-winding round-shaped traveller’s wristwatch water-resistant with snap-on case-back 24-hour bidirectional bezel; silver colour dial with centre-seconds and one horological complication:

· Instantaneous date of the month (aperture at 3 o’clock)

· Diurnal (day-time) and nocturnal (night-time) hours with a 24-hour (AM-PM) bezel (central hour index), allowing a second time zone to be obtained by turning this bezel.
