IWC Pilot's Watch Spitfire UTC Stainless Steel IW3251-06

It is the bracelet twin of the Spitfire UTC IW3251-05, which has the same 39 mm case, 12.5 mm thick, and the same black dial, on a strap. Both have a 20 mm lug width and a sapphire crystal. The silver-dial Spitfire UTC comes as the IW3251-10 on a strap and the IW3251-12 on a bracelet.

The Pilot's Watch UTC IW3251-01 and IW3251-02 share the 39 mm steel case size and black dial but are a millimetre thicker, at 13.5 mm. The platinum UTC IW3251-03 with a blue dial was limited to 500 pieces, and the two platinum Spitfire UTC Tim Mercer watches, IW3251-09/1 with a black dial and IW3251-09/2 with a silver one, are unique pieces.
