Curved Case Pins

WIS Curved Case Pins (18mm–24mm)
These precision spring bars feature a subtle, intentional curve that allows your strap to sit tighter against the case for a cleaner, more integrated profile. Perfect for straps that leave a small gap at the lugs, curved pins help your favorite leather, rubber, or fabric strap hug the case the way it was meant to — giving a more OEM-style fit and a smoother wrist feel.

Sizes available:

• 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm
  Choose the exact width that matches your watch’s lug size.

Why collectors use curved case pins:

• Closer case-hugging fit — reduces strap gap at the lugs

• Improved comfort — strap follows the natural curve of the case

• Cleaner aesthetic — more seamless, factory-like integration

• Easy upgrade — instantly elevates the look of most straps

A small detail that makes a big difference — especially for collectors who care about how a strap really sits on the watch.
