*by P***S on 13 September 2025*

Came in a small cloth bag inside a cardboard box rather than the nice metal case pictured in ad that I would be used to with G-Shock watches. Colour is also a much flatter Matt red than pictured. Had I seen it in the flesh before purchasing I’d probably have chosen something else. Watch itself colour issue and box aside is nice. Delivery time was good, a day earlier than predicted.
