This is the Sailmaster by RXW・ROCKX (Kent Trading). It is the RXW Sailmaster Second (Japan Movement), a completely limited edition model. The dial uses genuine shell. The red lightning-shaped hands are eye-catching and particularly cool. I recently purchased this on this site, but I have only displayed it in a case for viewing and have not worn it. Accessories include the original case. Since this is a used item, please refrain from purchasing if you are sensitive to such things. No returns or exchanges. I will wrap it in bubble wrap and pack it carefully.
