This is a very uncommon and fairly large vintage 1970s IWC measuring 32x34mm and the lugs extending to 38mm all in stainless steel with interesting quarter-turn case back. The caliber 3254 automatic winding movement was just serviced and is accurate. This original blue dial is elegantly refined and simple; having thin baton hands and matching steel markers. The correct winding crown by IWC is present. I think IWC vintage watches are truly undervalued, with my sentiments towards this model being the same.
