IWC Ingenieur Chronograph Classic Stainless Steel IW3808-04

It is the steel Classic IW3808-01 with a green dial in place of the silver one: the same case, stick-and-dot markers, stick hands and sapphire crystal. The IW3808 family also includes the red gold Classic IW3808-03 and the red gold Tribute to Nico Rosberg, IW3808-05, limited to 23 pieces. The Ingenieur Chronograph Custom models carry IW3808 references with letter suffixes, such as the IW3808-AC.

The movement is IWC's calibre 69375, which SJX described when the Ingenieur was redesigned in 2017: an in-house chronograph with a column wheel, Magic Lever winding and a 46-hour power reserve.
