Black Sharkskin Leather Custom Notched Strap For Seiko SNK063J5 Arabic Numerals Black Dial WATCH
The Seiko 5 SNK063J5 is a small fixed-lug field watch, and this owner wanted more texture than plain calf while keeping the leather flush to the case. We built a black shark skin strap, notched and cut to the customer's measurements for an 8.0" – 8.5" (20 – 21.5 cm) wrist.

Why these choices
Shark is one of the toughest exotic leathers, with a dense, tooth-textured grain and a natural sheen that reads as rugged rather than dressy. On a black-dial field Seiko it adds grip and character without color. See more in our shark skin and black strap ranges.
We cut it as a notched strap to the customer's measurements so the leather sits flush at the lugs, and sized it for a fuller 8.0" – 8.5" wrist. If your wrist runs larger still, the same builds go up to 12 inches in our extra-long range.
★★★★★
“Very good quality of the product — material quality, and the way it is made.”

FAQ
Is a shark skin strap durable? Shark is among the hardest exotic leathers and its grain shrugs off daily knocks better than smooth calf. It's a sensible everyday choice.
Can you make it for a larger wrist? Yes. This one was sized for an 8.0" – 8.5" wrist, and we build up to a 12-inch wrist on request.

Need a notched strap for your Seiko?
Many Seiko 5, King Seiko and vintage cases sit over the strap rather than beside it, so a plain rectangular strap end won't tuck under the case. A notched strap is cut so the end seats cleanly against it: centre-notched where the case cuts into the middle of the strap end, corner-notched where it cuts the corners away.
This build is centre-notched — order one here: custom centre-notched watch strap. If your case cuts the corners instead, you want the corner-notched strap. Either is cut to your watch's measurements, in any of our leathers. Or browse all Seiko watch straps, including the 19mm widths most Grand Seiko references take.
