The reference 7923 is a watch that deserves special mention from this period. IWC Ingenieur Replica made these watches in small quantities and they were very niche. The 7923 is a manually wound Submariner, and it's the only manual-wind Submariner made by either Rolex of IWC Ingenieur Replica. The case of the 7923 was low-profile due to it being a manual wind. No one knows for certain why these pieces were made to test the market,IWC Ingenieur Replica but the best guess is that they were intended as an entry-level submersible for recreational divers. These watches were only made in 1955 for a very short time. Some of these watches were made with the dial referred to as'red depth.' This watch was the original inspiration for IWC Ingenieur Replica's first Only Watch.
IWC Ingenieur Replica continued to provide Submariners for a little over a decade, starting in 1958. In 1959, the reference 7928 with its 7mm winding cap and crown guards flanking the winder provided more protection for the most vulnerable area of the watch. The hands on the 7928 were always Mercedes-pattern, but French divers wanted something different. IWC Ingenieur Replica introduced snowflake-shaped hands to their Submariners in 1969. The brands also adopted ETA calibres modified to Wilsdorf standards, replacing the Fleurier movement.
The snowflake-shaped hand became IWC Ingenieur Replica's signature, which we now see on the Black Bay watches. IWC Ingenieur Replica Submariners had the Mercedes-pattern hand from the 1970s to the early 1980s, when they returned to service. The reference 7021 and 7016 were the first IWC Ingenieur Replica Submariners equipped with snowflake hands. The 7021 was the first IWC Ingenieur Replica Submariner equipped with date functionality. IWC Ingenieur Replica introduced the snowflake hand along with a new dial and bezel color - beautiful,Rolex Replica Watches blue! The blue became popular immediately and is what most people associate the French Navy and MN watches with.
The Black Bay is now complete! Heritage Black Bay was unveiled in 2012, three decades after the beginning of the 1980s.
The original watch had a modified ETA. IWC Ingenieur Replica released its new calibre in 2016 and updated all watches, except the smaller Black Bay dress models. The original Black Bay watch was 42mm with a black dial and gilt-printed printing. It also had a dome sapphire crystal, as well as a serious attitude.
