Certina DS-2 Automatic, Ref. 5801 300N, Cal. 25-651, 1973

A blue dial and orange seconds hand give Certina DS-2 Automatic Ref. 5801 300N from 1973 its distinctive color contrast. The Swiss men’s watch combines a bold DS-2 case profile, applied hour markers and a date window at 3. Certina caliber 25-651 supplies self-winding mechanical operation, with the watch fully serviced and in excellent working condition.

Blue dial, orange seconds and date at 3

The blue dial has the rich appearance documented for this DS-2, with an orange seconds hand providing its separate sporting accent. Applied hour markers and a clean layout keep the face legible.

The date window at 3 adds practical everyday calendar information. The bold case and colored seconds hand preserve the expressive early-1970s design described for this watch, rather than the purely conservative presentation of a simple dress model.

DS-2 and the Double Security concept

The substantial case has the recognizable DS-2 shape and a solid wrist presence. Exact dimensions, case material and crystal details are unspecified; the documented character is its strong profile and purposeful construction.

DS stands for Double Security, Certina’s concept developed to improve protection against shocks, moisture and everyday wear. The DS-2 continued that robustness-focused approach, giving the line a more durable design philosophy than standard dress watches of its period.

Double Security describes the model’s protective design; no modern pressure-test or shock-resistance result is established for this individual watch. No current water-use rating is established.

Automatic caliber 25-651

Certina caliber 25-651 is the documented Swiss automatic movement inside this DS-2. It was used in a number of Certina models of the period and brings the self-winding convenience of automatic watches to regular wear.

The watch is fully serviced and in excellent working condition. It comes with a 12-month warranty; no measured daily accuracy or detailed servicing procedure is supplied.

A 1973 sports-dress presentation

As a 1973 birth-year watch, this example sits within its stated early-1970s design period. Strong case shapes, colorful accents and practical automatic movements formed the design context already documented for this DS-2.

This is a used vintage watch, with the actual dial, case, side profile, movement and visible back details shown in the gallery.
