I bought a 2004 Rolex Explorer II from Sierra Time Co. and the experience couldn't have been better. Max communicated quickly and shared the information I was looking for. After payment he shipped quickly, and the watch arrived exactly as described in his pictures. Overall a smooth buying experience, would highly recommend, and would buy from Sierra Time Co. again!
