Rolex 3330 chronograph retailed by Cravanzola, '40s

Stainless steel coin-edge round case, n.41581, rectangular pushers.Argenté dial, multi-scale, applied indexes and arabic numerals.Hand-winding movement.Leather strap and Rolex stainless steel buckle.Size: 37 mm.Notes: Reference 3330 is probably one of the rarest pre-Oyster chronographs ever made by Rolex. Produced in the 1940s, it features a large 37mm case which was unique for Rolex during this period; its twelve-hour register was an uncommon detail at that time as well.The present watch is in virtually unworn conditions, and has been consigned by a Madam daughter of the original owner, who purchased the watch in the early 40s and unfortunately died in battle few years later during the Second World War.A similar specimen, with salmon dial but without any retailer personalization, featuring the case serial number only 9 digits apart from this specific watch, has been sold in 2016 at Phillips "Start-Stop-Reset" auction for Chf 390,000.
