This is a VERY uncommon and fairly large vintage 70’s 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.
