Sinn 144 St S Anniversary II Limited Edition Watch Review

In celebration of the German watch manufacturer’s 60th anniversary, Sinn have introduced a 600-piece limited edition Sinn 144 St S Anniversary II watch that embraces many of the design cues found in the original 1974 model. In combining a 70’s-inspired aesthetic as seen in the tonneau-shaped case, hooded lugs and an integrated strap with some of their most advanced technologies, Sinn have delivered the best of both contemporary and vintage in the new Sinn 144.


It was the year 1961 when pilot and blind-flight instructor Helmut Sinn founded the company Helmut Sinn Spezialuhren in Frankfurt am Main focusing on the manufacture of navigation cockpit clocks and pilots chronographs. In continuation of this tradition, the Sinn 144 St S Anniversary II Limited Edition brings to life a historic model from Sinn’s archives from 1974 simply known as Sinn model 144. Dressed entirely in black chrome plating, the three-register chronograph was the archetype of a retro sports watch while still embodying the brand’s love for aviation. The sporty cushion-shaped case measured to 41mm in diameter and was paired with a matching all-black bracelet, mineral glass and a tachymeter and pulsometer scale.



The new Sinn 144 St S Anniversary II Limited Edition features all the hallmarks of the original including the familiar 41mm tonneau-shaped case with a clean, utilitarian look achieved by a bead-blasted finishing. The case is also coated in black, but rather than chrome-plating it utilises the brand’s modern Black Hard Coating which will prove far more scratch resistant and durable that the original. The case is also developed using Sinn’s famous TEGIMENT technology which again enables the exterior to be especially resistant to knocks and scratches.


Delivering further durability in the Sinn 144 St S Anniversary II watch is the addition of their Ar-Dehumidifying technology which promises greater functional reliability and freedom from fogging, working perfectly alongside the screw down crown and screw in sapphire crystal case back competent of a 200 metre water resistance. Sapphire crystal glass is also incorporated on the front end of the limited edition, protecting the matte black dial and ensuring optimal legibility thanks to anti-reflective coating treated on the interior surface.



The dial of the new Sinn 144 St S Anniversary II Limited Edition also carefully recalls the original 1974 model with a sporty, sloping tachymeter and pulsometer ring and a bi-compax layout and reverse panda colourway for the small seconds, 30 minutes counter and 12 hours counter. The matte black face stands out however for its vibrant new red accents included on the “60” marking on the tachymeter scale, the central chronograph seconds hand and hands on the chronograph subsidiary counters. The number 60 in particular captures attention adorned in daylight luminous paint while the indexes and hour and minute hands similarly draw interest at night decorated in luminescent coating.


Powering the chronograph complications, is the Concepto C99001 self-winding mechanism based on the trusty Valjoux 7750 calibre. Alongside 25 bearing jewels and a frequency of 28,800 semi-oscillations per hour, the Sinn 144 St S Anniversary II Limited Edition delivers a power reserve of approximately 48 hours, central hands for hours, minutes and chronograph seconds, small seconds, 30 minutes, 12 hours and a large day and date window at 3 o’clock. Through the sapphire crystal case back, the Concepto C99001 also provides some handsome embellishment with perlage decoration across the bridges, a striped rotor and blued screws.



As with so many of Sinn’s releases, the Sinn 144 St S Anniversary II watch is presented with more than just one strap option. In the box, it comes delivered on a H-link bracelet coated in Black Hard Coating but beside it you can also swap it onto a more minimalist black rubber strap fitted with a stainless steel folding buckle.
