FS: Sinn EZM 13 Divers Chronograph with Bracelet and Rubber Stra

Sinn EZM13 in almost new condition. I'm the original owner since March 2020 and wore the watch for about two weeks and decided it's not for me. It's an amazing watch with so much tech for the price and the central 1 hour chronograph is perfect, but I'm just not wearing it. The only reason I say almost new condition is that in wearing it, there are dome desk swirls on the buckle and a few swirls on the case back where the bracelet probably rested on the case at night. Other than that, it is like new. Warranty card starts March 2020. Includes the stainless steel bracelet as well as the Rubber strap. Includes all box papers, extra links (I sized it to a 7.5" wrist), strap changing tool and allen wrenches to adjust the bracelet your self (very easy).

Asking $2,650 + $30 shipping (PP fee on me). I will accept regular Paypal and cover the fee. Email me with any questions at

This watch gets its DNA from the hugely popular Sinn EZM 3 but adds a chronograph function using Sinn's SZ02 calibre.

The design similarities are quite clear when viewing the hands, dial, markers and diver's bezel.

The Sinn EZM 13 features a 41.5 mm bead blasted case in 316 L stainless steel with left mounted controls.

The Sinn EZM 13 is the all-new diving chronograph from Sinn, and features the in-house modified SZ02 movement with 60-minute register.

With 500 meters of water resistance, the Sinn EZM 13 has been tested to European diving equipment standards and certified by DNV GL, and is Mission Timer certified for optimal readability and use with crown and chronograph pushers relocated to the left side of the case.

When we spoke to Sinn's CEO Lothar Schmidt he indicated that this chronograph had been engineered to allow the use of the chronograph pushers underwater.

EZM Design - EZM 13

Sinn is known for their professional special forces watches, called the Einsatzzeitmesser (EZM - in English "Mission Timer") series. Sinn has long been a supplier of watches to various divisions of the German special forces, including the GSG-9, border protection, customs, military and special police divisions. Designing watches for these units carries a number of requirements, including resistance to shocks, water, magnetism and temperature changes among others.

There is also a functional requirement in that the watch must be highly legible and the controls must be both accessible and easy to use in extreme environments. This watch takes its place in the Mission Timer Series as the new Sinn EZM 13, and you'll notice that the crown and pushers have been relocated to the left side of the case as is typical for EZM watches.
