The Constantin Weisz, SFCBF MILSUB

In support of the Special Forces Club Benevolent Fund.

Own a piece of history while supporting a vital cause. In collaboration with Dirk Motz of Constantin Weisz, the Special Forces Club Benevolent Fund proudly presents a limited-edition replica of the iconic 5513 Milsub watch, created exclusively in aid of the Special Forces Club Benevolent Fund. Faithful to the “Military Submariner” legendary design as issued to members of the SBS and Royal Navy Clearance Divers during the 1970s, this watch features fixed bar lugs for ultimate security, a fully graduated bezel for precise dive timing, distinctive “sword” hands, and the authentic circle “T” marking.

Each watch comes with a classic grey NATO strap, or, for SF Club Members, a striking blue and green strap inspired by the Special Forces Club ties. The case back bears the MoD Arrow alongside the engraving “Special Forces Club Benevolent Fund, since 1947,” with the option to add your own initials for a personal touch. Inside, the watch is powered by the modern and reliable Miyota 9039 movement, combining classic military heritage with dependable contemporary performance.

Limited to just 100 pieces, this exclusive timepiece can be purchased via www.sfcbf.org/watch for a minimum contribution of £500. Every purchase directly supports the SFCBF and its mission to assist those who have served with distinction.

This limited edition is limited to only 100 pieces, capturing the rareness, spirit and functionality of such an iconic tool of service.

Because the watches are bespoke and made to special order, for SFCBF supporters, delivery will take up to 4 Months from date of order.

Key Features – Inspired by the MilSub Legacy:

• Fixed Military-Style Lug Bars: Like the original MOD-issued MilSub, the lugs are solidly welded to the case for maximum durability. This ensures reliability even under extreme combat or diving conditions.

  
  

• Reliable Mechanical Movement: At the heart of the watch beats a robust and precise automatic mechanical movement, ensuring performance without dependence on a battery — just like the originals.

  
  

• Domed Sapphire Crystal: The highly domed, scratch-resistant sapphire crystal echoes the acrylic domes of the 1960s while offering modern durability.

  
  

• Unidirectional Ceramic Bezel with Super-LumiNova Markers: The matte ceramic bezel is engraved and filled with luminous material for optimal legibility in low light or underwater — a nod to the fully graduated bezels of the vintage MilSubs.

  
  

• Super-LumiNova Dial Markings: The classic triangle, sword hands, and round hour markers are all filled with Super-LumiNova, providing high contrast visibility, just as required by military diving standards.

  
  

• 200m / 660ft Water Resistance: True to its diving watch heritage, the watch is rated for professional-grade water resistance.

  
  

• “T” Marking and Broad Arrow Dial: Honoring MOD watch dial specifications, the dial includes the circled “T” symbol for tritium-style lume (historically used on military watches), and the Broad Arrow, the traditional mark of UK government property.

  
  

• Military NATO Strap: Each watch comes on a durable, grey NATO strap — the military’s choice for secure, comfortable wear in the field.

The History

The Rolex Milsub 5513, short for "Military Submariner," is a rare and highly sought-after variant of the classic Rolex Submariner, developed specifically for the British Royal Navy in the 1970s. Based on the civilian reference 5513, the Milsub was modified to meet military specifications, including fixed bar lugs for added security, a fully graduated bezel for precise dive timing, and the distinctive "sword" hands for enhanced legibility underwater. The Milsub 5513 is celebrated not only for its rugged functionality but also for its deep connection to military diving heritage.
