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

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

This Certina DS-2 Automatic Ref. 5801 300m is a robust Swiss vintage watch from 1973, powered by the Certina Cal. 25-651 automatic movement. The DS-2 line is one of Certina’s most recognizable vintage series, known for its strong case construction, practical design and connection to the brand’s famous “Double Security” concept.

With its substantial case, automatic movement and 300m case marking, this example has the character of a serious 1970s Certina tool watch. It is a strong choice for collectors who appreciate vintage Swiss watches with real engineering purpose, rather than purely decorative dress-watch design.

Certina DS-2 Double Security Design

The DS-2 series continued Certina’s focus on durability and shock resistance. The “DS” name stands for “Double Security”, a concept developed to improve protection against shocks, moisture and everyday wear. These watches were built with a more rugged philosophy than standard dress watches of the period.

This Ref. 5801 has the distinctive DS-2 case style, with a strong 1970s profile and purposeful proportions. The design feels solid, functional and period-correct, reflecting the era when Swiss brands were producing practical automatic watches for active everyday use.

300m Case Marking

The case is marked 300m, giving this watch a more serious tool-watch character within the DS-2 family. While any vintage watch should be treated carefully today and not assumed water-resistant without modern pressure testing, the original specification shows the technical ambition behind the model.

This 300m marking is one of the details that makes the watch especially interesting for collectors. It separates the piece from lighter dress-style Certina models and places it closer to the brand’s sport and durability-focused heritage.

Automatic Certina Cal. 25-651 Movement

Inside the watch is the Certina Cal. 25-651, an automatic Swiss movement used in a number of Certina models from the period. It belongs to the brand’s respected mechanical movement family and suits the DS-2 concept well: reliable, practical and built for regular wear.

Automatic watches from this era offer the charm of traditional mechanical watchmaking with the convenience of self-winding operation. The Cal. 25-651 adds to the appeal of this DS-2 as a functional vintage watch rather than only a display piece.

Production Year: 1973

This Certina DS-2 has been dated to 1973, placing it in the heart of the 1970s tool-watch era. The early 1970s were a period of bold case design, strong mechanical movements and a growing interest in durable sports watches that could handle more than formal occasions.

As a 1973 vintage watch, this Certina can also be appreciated as a birth year watch, anniversary piece or personal collector’s item connected to that specific year.

Condition and Vintage Character

This is a vintage watch and should be viewed as a piece with age, history and character. The product photos show the exact watch offered, including the dial, case, caseback and movement details where visible. Please review all images carefully, as they form an important part of the description.

Any visible signs of age or previous use should be understood as part of the watch’s vintage identity. The appeal of a DS-2 is not only in its appearance, but also in the way it reflects Certina’s practical and durable approach to watchmaking.

Why This Certina DS-2 Stands Out

This watch stands out because it combines several desirable vintage Certina traits: the DS-2 case design, automatic Cal. 25-651 movement, 300m case marking and a production year of 1973. Together, these details create a watch with stronger collector appeal than a standard vintage dress model.

For someone looking for a vintage Swiss automatic with durability, character and a clear brand identity, this Certina DS-2 is a very compelling piece. It has the right mix of technical purpose, 1970s design and understated Swiss quality.

A Strong Vintage Certina Tool Watch

The Certina DS-2 Automatic Ref. 5801 300m is a distinctive 1970s vintage watch with real presence. With its Double Security heritage, automatic movement and robust case concept, it represents one of the most interesting sides of Certina’s vintage production.
