Lot 148

Certina, Swiss, "Automatic DS PH200M", Ref. 346.825, Cal. 25-651, 42 x 47 mm, circa 1975
A diver's large vintage automatic wristwatch with date
Case: steel, screw back with turtle and wave pattern, bidirectional rotating bezel with 60 minutes division, screwed crown. Dial: black with red crosshairs.
The letters "DS" stand for "Double Security", which, at the time, was achieved by fitting the movement to the case in a kind of "floating" installation using an elastic suspension ring and additional sealing . This was done in addition to the usual shock protection system - hence the double security. Extra-strong crystal was used and the caseback was also reinforced. The letters "PH" stand for "Pression Hydrostatique" (water pressure) and guarantees water resistance up to a depth of 200 m, i.e., 20 bar.
The original dial has luminous indexes in a charmingly aged vanilla colour. The luminous insert of the bidirectional bezel has taken on a beautiful greenish hue and among collectors the watch is appreciated as a highly desirable timepiece with a wonderful vintage look.
