Certina DS-2 Automatic, Ref. 5801 300m, Cal. 25-651, 1973
Certina DS-2 Automatic Ref. 5801 300m from 1973 combines a substantial case and black dial with Certina caliber 25-651. The Swiss unisex watch carries the documented 300m case marking and the DS-2 Double Security design identity. Its strong period profile and self-winding movement give it the purposeful character described for this example.
Substantial DS-2 case and the 300m marking
The case has the distinctive DS-2 style, with a strong profile and solid proportions. The black dial is the confirmed face color, while exact case dimensions, material, hand shapes and strap or bracelet details are unspecified.
The case is marked 300m. That inscription is retained as the recorded historical/design detail, without converting it into a current tested depth rating. This vintage watch should not be assumed water-resistant without modern pressure testing.
The marking and substantial case give this DS-2 its tool-oriented presentation.
Double Security design context
DS stands for Double Security, the Certina concept intended to improve protection against shocks, moisture and everyday wear. DS-2 continued the brand’s robustness-focused approach, with a more rugged design philosophy than standard dress watches of its period.
Its strong proportions retain the practical design of automatic watches from the early 1970s.
Certina caliber 25-651 and date display
Inside is Certina caliber 25-651, a Swiss automatic movement used in a number of Certina models from the period. Self-winding provides the regular-wear convenience associated with automatic watches.
A date display is recorded for the watch, with its position unspecified.
Condition, service and the 1973 date
This 1973 birth-year watch sits within the documented early-1970s setting of strong cases, durable sports-watch designs and practical automatic mechanisms. Its actual dial, case, caseback and visible movement details are shown in the gallery.
This is a used vintage watch. It is fully serviced and comes with a 12-month warranty.
