Longines HydroConquest XL 48 mm Chronograph watch. The dial is 48mm, and the buttons add an additional 7mm. But this simply doesn't give you any idea of how heavy it is, or how high it sits on your wrist. You can easily imagine why this was a short-run model for Longines - most people would definitely gravitate towards the 41/43mm models instead Comes in a luxury wooden Longines box with booklet Please note: You can't manually change the date with the crown. I have tried to but when the crown is pulled out in the date changing position the crown just turns and the date wheel doesn't turn. However, the date does change automatically after midnight through the normal timing of the watch. Comes on a brand new Longines bracelet. Just purchased this for £205 (see photo of receipt), comes with spare links and also comes with the Longines rubber strap The dial is 48mm, and the buttons add an additional 7mm.
