Headquartered at Frankfurt am Main, German brand Sinn was founded in 1961 by Helmut Sinn. From the earliest days the brand has focused on producing quality dive and pilot pieces with a strong emphasis on streamlined legibility.

Reliability and protection from the elements—you can expect this and so much more from the Sinn EZM 3 Diver. 

As part of the Mission Timers (Einsatzzeitmesser or EZM) line of watches you will enjoy straightforward, purpose-driven design decisions that make legibility—deep under the waves or safe on land—a priority.

First, this is a true dive piece. Look for a magnificent 500 m / 50 atm water resistance, screw-down winding crown, and solid screw-down caseback. The ratcheted minute-marked bezel provides a luminous key mark for added safety when diving.

In other interesting ways this piece strives to the utmost to preserve the integrity of the timepiece. For example, Ar-Dehumidifying technology ensures reliability and prevents fogging while Temperature resistance technology ensures reliability from -45 degrees C up to +80 degrees C. In addition, you also have a fabulous magnetic resistance to 80,000 A / m.

Peer through the scratch-resistant sapphire crystal and we see how the matte black dial showcases luminous markers and hands with a date window subtly nestled between 3 and 4. A stop seconds function allows you to easily stop the seconds arm when setting the time.

Measuring 41 mm in diameter and 12.3 mm in height, the bead-blasted stainless steel case rests upon a nylon strap with a tang buckle (an extra stainless steel bracelet is included). Note the unique left-side placement of the winding crown for maximum comfort.

As a self-winding automatic watch, the Sellita SW200-1 caliber beats at 28,800 vph and possesses 26 jewels.

Adding unique pieces to one’s collection is always a thrill, and we are confident that this Sinn EZM 3 Diver will make a wonderful addition to your collection.
