Rare Item: RADO Automatic DiaStar, Working, USED Men's Wristwatch Rado DiaStar Automatic Tungsten Carbide, Sapphire Crystal This automatic model is a rare item, with few available. I observed the automatic movement for 3 days, and it's running with almost no daily variation. Calendar change and time adjustment confirmed. The original strap is in good condition. Case width is 30mm. The wrist size can be adjusted. This is a secondary/tertiary market item and has been stored by a non-professional, so it is not new. Please be aware of minor scratches and stains. Please refrain from bidding if you are concerned about fine details or are looking for a perfect, mint condition item. Please refer to the images and no claims will be accepted.
