GST Chronograph Automatic : IW370713

The IWC Aquatimer GST Chronograph Automatic, reference IW370713, is a notable timepiece within the brand's collection, released in 1999. It features a stainless steel case with a solid caseback, measuring 39.7 mm in diameter, which houses the self-winding caliber 7922, based on the Valjoux 7750 movement. This particular model sports a clean white dial with an English day disc, providing functionality and readability. The design reflects a sporty aesthetic typical of the Aquatimer collection, yet it maintains a level of sophistication that is often associated with IWC watches. The integrated bracelet is also crafted from stainless steel, ensuring both durability and comfort for everyday wear. As part of the GST series—acronym for gold, steel, titanium—this watch was one of several configurations available before its discontinuation around 2003. Its timeless design and reliable performance make it a noteworthy example of late 1990s horology.
