BEFORE YOU ORDER FROM AUSTRALIA

Two things are worth checking on a piece like this: the case diameter against the wrist you are buying for, and whether the bracelet or strap can be sized without a specialist. Both are listed above. If you are comparing references, note that Australian pricing already reflects landed cost, so the figure you see is the figure you pay.

Buying from Australia — all prices are shown in AUD. Delivery is domestic and returns are handled by our Australian team, so you are not posting a watch back overseas if the fit is not right. If you want to compare before deciding, our collection pages group every model by brand.
