WMT Royal Marine – Royal Navy Edition / Heavy Aged

A Tribute to a Legend: The British Royal Navy Edition

A true hybrid of a military and diver's watch, we rebuild a classic through our Heavy Aged Project. Featuring components meticulously aged by hand, this piece resurrects a definitive 1950s design. This iconic silhouette was originally born when the Ministry of Defense sought a highly reliable and rugged timepiece to become the standard-issue for the Royal Navy's relatively new division of underwater combatants.

Key Features & Historical Heritage:

  • The Iconic "T" Mark: The circled "T" above six o'clock is a direct tribute to the legendary British Royal Navy diver's watch. Dating back to 1957, this mark denoted that the highly dangerous radium lume on the hands and indexes had been replaced with the safer Tritium. Today, we honor the look while using modern and completely safe Luminova.
  • Built for the Deep: Paired with a set of large, distinctive sword hands and a big crown—features originally engineered for effortless operation and legibility underwater.
  • Hand-Processed Patina: WMT has applied a heavy, vintage-processed patina across the watch, giving it a beautifully rugged, battle-tested aesthetic.
  • Reliable Caliber: Powered by the robust, Japan-made NH35 automatic movement.
  • Military Packaging: Includes a military-style canvas pouch proudly stamped with the traditional Broad Arrow symbol.
