Solid CuSn8 Bronze watch buckle 18mm wide Please note, Bronze is a reactive material and will oxidise and patina overtime. The buckles come shiny; but will v quickly oxidise, possibly even whilst in transit (despite my best efforts to not allow this to happen) to you so please do not purchase one if you are not expecting this finish. Please note I have 20mm versions in another listing. These were purchased for various personal watch projects that I have ongoing but sadly now have little time to complete
