About this reference
The IWC Ingenieur reference 9225 is an 18k yellow gold timepiece produced during the mid-to-late 1980s as part of the "Skinny" Ingenieur generation. Collectors value this reference for its 34mm Gérald Genta-inspired case design and its use of the ultra-thin caliber 2102, a quartz movement based on the ETA 210 series. This specific reference is noted for its integrated solid gold bracelet and the "SL" branding on the dial, signifying its lineage within the Steel Line heritage despite its precious metal construction. Due to low production volumes for solid gold variants during this era, the 9225 is relatively rare compared to its steel counterparts. On the secondary market, prices typically range from $12,000 to $18,000 depending on bracelet stretch and the presence of original documentation. A notable production detail is the use of a screw-down crown and sapphire crystal, maintaining the line's technical specifications.
