1952 IWC 'Mark XI' 6B/346 RAF Military Watch 36mm Cal. 89
Here we have a classic 1952 IWC 'Mark XI' 6B/346 RAF Military Watch Cal. 89, used by RAF Navigators to calculate the exact longitude and latitude of the aircraft alongside a bubble sextant. It's 36mm stainless steel round case has a soft iron cage that is an anti-magnetic housing for the movement. It curves over your wrist with tapered lugs and fixed spring bars, perfect for fitting NATO straps. The curved flanks lead to a lug-to-lug length of 46mm and a case thickness of 11.5mm, ensuring a comfortable fit on your wrist. On the right side, there is a coin-edged crown. The smooth stepped bezel holds a domed crystal above a matte black dial. An outer minute track surrounds Arabic numerals, Tritium-coated batons and a triangle at 12 o’clock marking the hours. A baton hour hand and a syringe minute hand are filled with Tritium lume and complemented by a teardrop counterweighted second hand. At 12 o’clock, we have the International Watch Co. motif and the Broad Arrow (pheon), the mark indicating British Government Issue property. At 6 o’clock, we have the ‘T’ in a circle indicating the use of Tritium lume, completing this military issue timepiece. On the reverse, a screw-down solid case back engraved with the Broad Arrow (pheon) 6B/346, 2185/52 signifying its RAF Navigator reference and military Store number. Inside a manually wound IWC Cal. 89, 17 jewels, beating at a leisurely 18,000 beats per hour with hacking seconds. This workhorse movement was designed by Albert Pellaton, Technical Director of IWC, and launched in 1948 for the IWC Mark XI Pilots watch ordered by the RAF. It remained in production until 1979. It comes paired with its well-suited 18mm NATO strap & older folded end leather strap.
