Swiss luxury watchmaker Hublot has released a limited edition watch featuring a Powder Metallurgy Damasteel case. The Big Bang Unico Gourmet watch forms part of Hublot’s Gourmet range, and its distinctive material choice is influenced by the metal used in high-end chefs’ knives.

Damasteel is based on the traditional Damascus steel process, and today is made from gas atomised metal powders that undergo a Hot Isostatic Pressing stage, followed by forging and rolling steps before twisting or coining.

The particular type of Damasteel used for the Unico Gourmet consists of 304L and 316L, both stainless steels that are widely used for watch cases. The Damasteel is etched with various acids to bring out the layered texture, as each type of steel reacts differently to the acid. The darker layers are 304L while the pale layers are 316L.

The novel Powder Metallurgy process was developed by Sweden’s Erasteel, who later formed the company Damasteel. The material is popular with knife makers, as it blends great strength with the characteristic patterned finish of Damascus steel.

The Big Bang Unico Gourmet features a 42 mm watchcase and a self-winding chronograph movement. It is waterproof to 100 metres and costs around €25,200.
