this is an extremely rare IWC 1832 SL Jumbo from the mid 1970s in steel and gold. The watch features a very interesting story which is an important part of IWC´s special horological history. The 1832 was delivered out with an automatic caliber 8541, just like every 1832 Jumbo. Up on request, a customer could also ask for an IWC quartz caliber 2405 in the early 1980s, which was the much more desirable technique at that time. Unlike today of course. The 1832 in steel gold is a very rare watch in general but only a handful must have received a quartz caliber upon request back in the days. When we purchased this 1832, it was one of them. So we contacted IWC, who are still aware of the service they offered to customers in the 1970s/80s, and asked them if they could still built it back to an automatic watch today, just like it once was born as. And the stunning answer was yes! So for the last 6 months this piece was with IWC and was finally been equipped back again with a brandnew C.8541B automatic caliber, dial, handset and crown (at 4371,00€). The 39mm case stayed untouched and still appears in it´s original unpolished and beautiful Genta shaped condition. The watch comes with all 2022 service papers from IWC (incl almost 24 months guarantee on the works), a nice black box and an additional link, which can extend the 1832 to a wrist circumference of 18,5 cm. One of Genta´s big three with a rare individual Provenance.
