The Seiko 4336-8060 is generally listed at about 35–36 mm case diameter , 40–41.5 mm lug-to-lug , 18 mm lug width , and roughly 10–11 mm thickness. I found one listing that gives a weight of 73 g including the wristband , but weight can vary a bit depending on the strap or bracelet fitted.

Quick Scoop

  • Case size: about 35–36 mm.
  • Lug-to-lug: about 40–41.5 mm.
  • Lug width: 18 mm.
  • Thickness: about 10–11 mm.
  • Weight: about 73 g with wristband, from one listing.

Note

Because this is a vintage Seiko, different sellers sometimes measure it slightly differently, especially if the crown, crystal, or strap has been changed. The safest takeaway is that it sits in the small-to-medium vintage dress watch range.

TL;DR

Best estimate: 36 mm case, 40–41 mm lug-to-lug, 18 mm strap size, around 10 mm thick, and about 73 g with strap.
