Black Epsom Leather Custom Notched Strap For Seiko 5 Arabic Dial, REF. SNK063J5 Watch
The Seiko 5 SNK063J5 — the black Arabic-dial variant — is a favorite first mechanical, and this owner wanted a leather strap that sat cleaner against the case than a pass-through band. We cut a center-notched Epsom strap to the customer's measurements, sized for a 6.5" – 7.0" (16.5 – 18 cm) wrist.

Why these choices
Epsom is the fine, stamped calfskin used for structured leather goods — lightweight, scratch-resistant and firm-handed, so it holds a clean edge on a small case like the SNK. In black it keeps a field watch versatile without adding bulk. It sits in our Epsom leather and black strap ranges.
We built it as a center-notched strap, cut to the customer's measurements so the leather seats against the case rather than standing off it. A notched fit has to be exact, so we size to a measured length — here, a 6.5" – 7.0" wrist.
The owner already planned a second color, which is the point of a made-to-order strap: the same pattern in any leather or color.

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.
