Replica Patek Philippe Aquanaut 5164A — 40.8 mm Travel Time, Black Dial, Steel
The 5164A is the dual-timezone Aquanaut. Patek Philippe introduced this reference in 2008, adding the Travel Time complication to the Aquanaut platform — caliber 324 S C FUS drives local and home time through two pushers flanking 6 o’clock and a second crown at 8. The home-time hand sits behind the local hour hand, both visible simultaneously without subdials. The -001 suffix designates the black embossed dial. This replica Patek Philippe Aquanaut Travel Time is built in 904L steel: case, bezel, crowns, pushers, clasp.
Dual timezone at 40.8 mm — two hour hands, two pushers at 6, a second crown at 8, and the black chequerboard dial reads local and home time on one face.
Case & Dial
40.8 mm diameter, 11.4 mm thick — the Travel Time module adds roughly 3 mm over the base 5167. Rounded octagonal bezel with polished bevels, satin-brushed flanks. Two recessed pushers at 6 toggle between local and home time display. Second crown at 8 adjusts the local hour hand in one-hour jumps. Sapphire caseback, AR-coated.
Black embossed dial with the Aquanaut chequerboard pattern — a grid of raised squares pressed into the surface. Applied luminous baton markers. Two overlapping hour hands: main local time in front, skeletonised home-time hand behind. Date at 3. Day/night indicators for home time visible through two apertures. Under angled light the embossed grid catches shadow and adds depth.
Strap
Black “Tropical” composite strap with fold-over deployment clasp. The composite surface carries the same chequerboard pattern as the dial — a signature Aquanaut detail. The Nautilus Travel Time 5990 adds a flyback chronograph to the dual-timezone formula; the Aquanaut 5164 keeps it simpler: timezone only, no chrono, lighter on the wrist.
Movement
Caliber 324 S C FUS, automatic, 28,800 vph. 45+ hour power reserve. The FUS module drives independent local-hour adjustment. Through the caseback: Côtes de Genève, perlage, blued screws. SuperClone tier: ±8 sec/day. Full specs on our FAQ page.
