The brand is using Sinn Technologies to ensure precision and longevity. The collection includes a variety of calibres and appearances, but each model is a high-quality, high-performing timepiece. Sinn is famous for pushing their watches to the limit, and this is brought to life in the EZM Collection, with every watch being built to withstand extremely adverse conditions. 

Core Features of the EZM Collection:

• The EZM collection features a variety of mission timers. The mission timer appearance ensures clear readability, even in adverse conditions. 
• Every watch in the collection features a mechanical movement. 
• The watches all feature a matte black dial so that the white, luminescent indices stand out and are clearly readable. Every watch features sapphire glass to protect the dial. 
• Each watch in the collection has been treated with temperature resistance technology, making them functionally reliable between -45˚C and +80˚C. 
• The EZA watches are all treated with Ar-Dehumidifying Technology to make them long-lasting and resistant to fogging. This ensures that the dial is readable, even if the watch is exposed to sudden temperature changes. 
• All of the watches in the collection are waterproof and pressure-resistant to at least 20 bar and are also resistant to low pressure. 
• Each model has a captive bezel, precisely designed for the intended use of each specific model.  

Model Specifications 603.020 H-LINK:

• This diving watch is powered by an SW 200-1 self-winding mechanism. It uses 26 bearing jewels and 28,800 semi-oscillations per hour to power the watch. This movement also has a seconds stop function and is anti-magnetic as per DIN 8309. 
• The watch has magnetic field protection of up to 80,000 A/m. This model uses an additional, solid soft iron sheath around the movement to protect the accuracy of the watch. 
• The black dial features a date display between 3 and 4 o’clock. The date, along with other diving non-essentials, is muted in red. 
• The dial is framed by a case made of bead-blasted stainless steel with a black hard coating on a TEGIMENT Technology basis.   
• The diver’s bezel with minute ratcheting features a luminous key mark. 
• This model is water-resistant and pressure-resistant to 500m diving depth (50 bar), certified by DNV GL. It meets the technical requirements for waterproofness, as set out in standard DIN 8310 and according to the technical demands for the diving norm DIN 8306. The watch is tested based on European diving equipment standards EN 250/EN 14143. The use of double O-rings on the screwable crown further the waterproofing.  
• The case is filled with a protective gas in order to keep ambient oxygen and other corrosive gases at bay. An integrated drying capsule absorbs inevitable humidity in the case. 
• The crown is positioned at 9 o’clock so it does not put pressure on the back of the hand. 
• The watch has a case diameter of 41mm, a band lug width of 20mm and a case thickness of 12.3mm. It weighs 81 grams without a strap. 
• The indices, hour, and minute hands are coated with luminescent colour.
