About Sinn

With its headquarter in Frankfurt am Main, Sinn Spezialuhren was founded in 1961 by a WWII pilot and flight instructor, Helmut Sinn. The company focused on the manufacture of navigation cockpit clocks and pilot chronographs and sold these through direct selling, bypassing retailers. The reputation of good quality at excellent price spread rapidly among pilots and placed Sinn among the desirable brands specializing in tool watches.

Throughout the years, Sinn engineers and watchmakers developed several innovations, such as HYDRO Technology introduced in 1996, which guarantees that diving watches will be completely free of fogging, extreme pressure resistance and great underwater readability. In 1998, Sinn perfects Ar-Dehumidifying Technology by combining it with SINN Special Oil 66-228 to create Temperature Resistance Technology which helps ensure that watches remain functional at temperatures of between −45°C and +80°C.

Another notable Sinn invention is DIAPAL, a technology making use of special combination of materials, resulting in a lubricant-free lever escapement.

2003 was the year when Sinn introduced its TEGIMENT coating technology and in 2012, they announced the TESTAF certification for pilot watches.

Let us walk you through the new Sinn models presented at the 2014 Baselworld.

EZM 9 TESTAF pilot watch

EZM 9 TESTAF pilot watch

TESTAF is a technical standard for pilot watches developed by the faculty of Aerospace Technology at the Aachen University of Applied Sciences in collaboration with Sinn Specialuhren. For a pilot’s watch to be TESTAF certified, it must satisfy a whole list of stringent requirements: readability in daylight and in darkness, accuracy and power reserve, operability, resistance to shock sudden temperature changes, water and magnetic fields, secure strap fastening, etc. TESTAF is quite a fascinating initiative and it deserves to be presented in more details in an upcoming story. If you’re curios to find out more about it, head over to www.testaf.org (page in German).

As its name shows, EZM 9 TESTAF has successfully passed the above mentioned requirements. Its bead-blasted titanium case is highly scratch resistant, thanks to TEGIMENT, a surface hardening technology developed by Sinn. The watch is measuring 44 mm in width, 12 mm thick and has a lug width of 22 mm. The matte black dial and luminescent coated white indexes offer excellent visibility.

EZM 13 diving chronograph

Sinn EZM 13 diving chronograph

This piece was designed to be used as a tool by professional divers. It is water resistant to 50 bar (500 m), certified by DNV GL, a German company specialized in technical testing and certification for the energy and maritime industries.

The EZM 13 features an integrated SINN SZ02 chronograph movement (based on Valjoux 7750). Boasting a 60-minute – rather than the standard 30-minute – counter at 6 o’clock, this SZ02 movement enables direct and easy reading of the minutes right through from 0 to 60.

To offer more freedom of movement for the diver’s hand, the crown and the push buttons are placed on the left.

The EZM 13 is 41.5 mm wide and 15 mm thick, with a lug width of 20 mm.

6052 the Frankfurt Financial District Watch with calendar week display

Sinn 6052 the Frankfurt Financial District Watch with calendar week display

The 6052 is a classic looking chronograph with a little surprise under its (wearer’s) sleeve: a calendar week display – the first special function of its kind to be used in a watch with this display configuration. In addition to the calendar week, the dial also displays the day, date and month. It is powered by Sinn modified Valjoux 7751, the SZ03, with a 60-minute counter replacing the 30-minute counter.

To enable intuitive reading of the calendar week at a glance, the week display is now featured alongside a 60-minute display.

The polished stainless steel case has a diameter of 41.5 mm, 14.5 mm high and a lug width of 22 mm.
