Revealing the elegant movement of the various retrograde hands, the Longines Master Collection Retrograde Dual Time Zone watch houses an exclusive movement developed specially for Longines.
With a diameter of 16½ lines and 25 jewels, the self-winding calibre L698.2 (ETA A07 L21) beats at 28,800 vibrations per hour and has a power-reserve of 48 hours.
Apart from displaying the hours and minutes, this timepiece boasts four retrograde functions, namely the day of the week at 12 o’clock, a date aperture on the right-hand side of the dial, a small seconds at 6 o’clock and a second time-zone with a 24-hour scale on the left. The silvered dial hosts eleven black Roman numerals and six blued steel hands.
The Dual Time Zone version from the Longines Master Retrograde series is available in two case sizes: 41mm and 44mm. The stainless steel case features a crown at 3 o’clock and two discreet correctors. It also has a transparent back cover, offering the view of the movement beating inside the watch.
Fitted on a brown alligator strap with a folding safety clasp, this Longines Master Retrograde watch is water-resistant to 3 bar (30 metres).
The Longines Master Retrograde collection also offers other versions featuring moon-phases or power-reserve display
