Certina Heritage Collection watches

The Certina Heritage Collection brings together watches built around the Swiss brand's DS name: the DS PH200M and DS Super PH500M divers, the DS Powermatic 80, the DS-2 and the DS Chronograph Automatic. Certina was founded in Grenchen in 1888 by the brothers Adolf and Alfred Kurth and joined the SMH Group, now Swatch Group, in 1983. DS stands for Double Security, a concept the company has used since 1959: the movement is suspended in a reinforced case so that it can move under impact, and the turtle on Certina's logo stands for protection against water and shocks.

The DS PH200M is a reissue of the 1967 diver of the same name, reference 5801 117, which was water resistant to 200 m and had a screw-down crown. The modern watch, shown at Baselworld 2018, grows from about 40.5 mm to 42.8 mm, keeps the date at 3 o'clock and the 200 m rating, and has a rotating diver's bezel and the Powermatic 80 movement with an 80-hour power reserve. C036.407.16.050.00 has an acrylic crystal and a 13 mm case; references such as C036.407.16.040.00 switch to sapphire and an 11.9 mm case, and a 39 mm DS PH200M has mother-of-pearl dials.

The rest of the range spans dress, sport and dive watches. The DS Powermatic 80 is 41 mm wide and 10.9 mm thick, with dials from white and blue to green, brown and champagne. The DS-2 Powermatic 80 is a 40 mm steel watch. The DS Chronograph Automatic 1968 is a 42.5 mm chronograph with a rotating bezel, in steel or with a black PVD coating, alongside a 42.8 mm DS Chronograph Automatic with a silver dial. The DS Super PH500M is a 43 mm, 14.95 mm-thick diver, including a blue Sea Turtle Conservancy edition (C037.407.18.040.10).
