Mido Multifort watches

The Mido Multifort is the oldest collection of Mido, the Swatch Group brand founded in Biel in 1918, and has been made since 1934. The original was a water-resistant, shock-resistant and antimagnetic watch, its crown sealed by a treated natural cork gasket that Mido later named Aquadura. Electrical Testing Laboratories in New York put six of them through more than 1,000 hours in fresh and salt water and altitude tests up to 16,600 metres; only one stopped, at 13,300 metres.

The modern Multifort is a steel sports watch with a vertically striped dial, a long-running feature of the series. The Gent is the 42 mm model and the Chronograph its 44 mm counterpart, with a tachymeter bezel on the Chronograph Adventure and a 0–60 bezel on the Gent Adventure. The Dual Time and Power Reserve models share the 42 mm format, and several models also come in PVD-coated steel.

The Multifort Chronometer, announced in 2018, was the first Multifort with Mido's Caliber 80 Si, a COSC-certified movement with a silicon balance spring and 80 hours of power reserve. It has a 42 mm three-piece case with a day and date at 3 o'clock, a domed sapphire crystal, a screwed display back and 100 m water resistance, in steel, two-tone or black PVD.

The Patrimony models look back rather than forward. The 42 mm Patrimony Chronograph is a tribute to a Mido of 1937, with narrow round pushers, no crown guards and Mido's ETA-based Caliber 60 behind a display back; the rose gold PVD version has a domed blue dial, the steel one a black dial. The 40 mm three-hand Patrimony came first. At the other end, the Gent Escape is a 44 mm watch in black or khaki, and the Gent Mechanical Skeleton is an openworked 44 mm titanium edition limited to 999 pieces.
