This is a Longines Hydroconquest watch with a stainless steel bracelet (L3.742.4.56.6). It comes with the original box, instructions manual, warranty card, and extra links. The original receipt can be provided (it is slightly faded unfortunately). The watch was purchased in August 2018. The watch works perfectly, though it is clearly in 'used' condition (a testament to how much I liked wearing it!).
