The case measures in at 33.5mm in diameter (roughly 37mm lug-to-lug). The lug width is 18mm, adding another value proposition based on the ability to change straps frequently. Due to the raised snap on caseback, it has a slightly robust feel. When worn on a bracelet, such as this period correct beads of rice example, the watch wears very flush to the wrist due to the downturned lugs.
The case has possibly seen a polish at some point. However, it appears to have been done lightly, maintaining the true structure of the watch. The watch features its original signed Seamaster crown which is well proportioned to engage with.
