An Introduction to Sinn Watches

We have to go back to 1961 when Helmut Sinn founds the company “Helmut Sinn Spezialuhren” in Frankfurt. The company’s focus at that time was the manufacture of navigation clocks and pilot chronographs. There are few companies in the horological arena with such an impressive history of innovation, exploration and certification. Lothar Schmidt, an engineer himself, bought Sinn in 1994 bringing with him a burning desire for technological development. Innovative features such as Sinn Hydro – filling the watch dial and hands void with an oil to prevent reflection when under the water …..

The Sinn 140 S in outer space

We all know that Omega Speedmaster watches have been worn in space, but they’re not the only brand with that claim. In 1985 the German physicist / astronaut Professor Dr. Reinhard Furrer wore a Sinn 140 S during the D-1 spacelab mission. In doing so he proves the watch’s self-winding mechanism works even in the weightless conditions of space.

Sinn U1 – cast from German Submarine Steel

One thing that really sets our teeth on edge at ChronoDivers is when an alleged “dive watch” has hands colour coordinated to the watch’s dial. White hands on a white face might look quirky in the office, but try and read them under water! The Sunn U1 range of divers’ watches have highly contrasting dials and hands. Most models feature a matt black dial and contrasting white hands and indexes. Many models have the optional extra of Sinn TEGIMENT (a patented stainless steel case hardened technology providing extremely effective protection from scratches)

U1 Gallery

A combination of images from Sinn’s media library. The final watch here is a FULL SET Sinn U1 discovered on eBay complete with box and papers. Notice the position of the U1’s crown at the 4 o’clock position – this prevents pressure on the back of the hand when bending the wrist. The first two watches are coated in black hard coating PVD – in conjunction with TEGIMENT anti-scratch treatment.

Certified by DNV GL

GNV DL tests and certifies Sinn diving watches – ensuring they are both water resistant and pressure resistant. Their testing criteria is so strict it qualifies for certification in accordance with the European Standards for Diving Equipment. The Sinn U1 is compliant with European diving device standards EN250 and EN14143

Sinn UX S Combat Swimmer (EZM 2B)

An accolade that many dive watch manufacturers strive for is the adoption of their timepieces by the National Armed Forces. Germany’s Commando Frogman Force KSM (Kommando Spezialkräfte der Marine) are one such division endorsing Sinn divers watches. The Sinn Mission Timer UX S Combat Swimmer (EZM 2B) is worn by all KSM divers. An  international tender was placed by the Federal Office of Bundeswehr Equipment (BAAINBw) with strict guidelines to how the watch must perform. The Sinn UX was selected over the competitors watches – proof enough that this is a very competetent, professional underwater timepiece.

Development of HYDRO Technology

Visibility of a dive watch at depth is second only to water resistance. Sinn developed their own HYDRO Technology – introduced in the Sinn 403 HYDRO for the first time. This innovative design feature provides freedom from fogging and optimal readability at any angle.

Compliance to European Diving Equipment Standards

SINN manufacture diving watches in compliance with European diving equipment standards – they were the first company to do so. They were also the first to put their dive watches through third party testing to certify them for pressure resistance, water resistance and resistance to fogging.

Alternatives to Sinn diving watches

If the Sinn brand appeals then please also consider a diver’s watch from either Doxa, Oris, Tissot or Longines. Like Sinn, the range of Doxa dive watches in underappreciated and sometimes even overlooked. Most popular in their dive watch collection are the Doxa Sub 200, the glorious Doxa Sub 300T (with no-decompression bezel timer) and, our favourite, the reborn Doxa 600T built from marine grade stainless steel. Next we’d recommend a trip over to the Oris Dive watch collection. The most popular models in their dive collection are the Oris Aquis (WR to 300m – 1000m) and the Oris Divers Sixty Five (WR to 100m). A collection of competent timepieces with a product for all users from outdoor beach life (Oris Sixty Five) to full on professional diver (Oris Aquis Depth Gauge).

If nothing their grabs your attention then wander over to the more traditional, yet equally desirable range of dive watches from Tissot and Longines. Tissot is a brand with a long and intimate relationship with the sea and in particular – divers watches. Join us as we take the plunge and dive in to the Tissot Seastar diver’s watch collection. Most popular are the Tissot Seastar 1000 and the deep diving Tissot Seastar 2000 with Powermatic 80 automatic movement. Longines is another company with a long relationship promoting outdoor life, sports and adventure. Like Rolex, Blancpain and Breitling – Longines entry in to Diver’s watches goes back to 1959! The new Longines Hydroconquest is their most desirable timepiece. A watch dedicated to men and women who demand high end performance from their timepiece without compromising on technical innovation and elegance.
