Laurent Ferrier Sport Traveller Slate Grey Titanium – Dual Time, Micro-Rotor, 72h (4K)

When travel becomes a discipline, time becomes a tool. In this WatchAdvisor video (in 4K), we take a close look at the Laurent Ferrier Sport Traveller in slate grey opaline, housed in a 42mm Grade 5 titanium case with 100m water resistance and an integrated titanium bracelet.  The Traveller idea — executed for real-world movement The Sport Traveller is built around an instantly usable dual time-zone system: two push-buttons on the left side adjust the local hour hand in one-hour jumps—forward at 10 o’clock and backward at 8 o’clock—without stopping the watch. Home time sits at 9 o’clock, the date at 3 o’clock, and small seconds at 6 o’clock.  New manufacture calibre LF275.01 Inside beats the LF275.01 automatic, offering 72 hours of power reserve at 4 Hz (28,800 vph). It uses an off-centered micro-rotor winding system with a 950 platinum oscillating weight, plus a unidirectional ball bearing designed to improve resistance to shocks and vibrations. Bridges feature a horizontal satin finish with ruthenium treatment, and key elements of the micro-rotor bridge are hand-finished and mirror polished.  Dial and case details that matter The dial is slate grey with powder-grey transfers and discreet “Sport Traveller” text; the white-gold hands and indexes carry light green Super-LumiNova for legibility day and night. The titanium case combines contrasting finishes—circular satin on the bezel, polished sides, and vertical satin brushing on the case middle—matched by an integrated three-link bracelet and titanium deployant clasp.
