Launched in 1974, model 144 is one of the most traditional watches in our range.

To mark our company’s 60th anniversary, we are now introducing a special limited edition of 600 timepieces in the form of the 144 St S Anniversary II. This model clearly demonstrates the timelessness of our instrumental, technical watches. The 144 St S Anniversary II is also a fine example of how we are constantly developing our classic timepieces. For example, the old 144 featured a black chrome-plated case with mineral glass and was only pressure-resistant up to 5 bar.

The 144 St S Anniversary II takes things to the next level in many respects. For instance, this timepiece is equipped with a wide range of technical features, is resistant to low pressure, waterproof and can withstand pressures of up to 20 bar. Ar-Dehumidifying Technology ensures greater functional reliability and freedom from fogging. The bead-blasted surface of the stainless-steel case has also been hardened using TEGIMENT Technology, making it especially scratch-resistant. This type of technology forms the basis for the high-quality Black Hard Coating. Typical of a 144, our anniversary edition also features a combined tachymeter and pulsometer scale.

The prominent positioning and intuitive readability of the white counters for the stopwatch minutes and seconds give this anniversary edition a modern look, without forsaking its traditional feel. As a reminiscence of the company's anniversary, the number 60 of the pulsometer scale has been applied in orange-red daylight luminous paint.

Our limited edition 144 St S Anniversary II with unique numbering comes in a fine case with a black solid bracelet and a black silicone strap.
