Black Epsom Leather Custom Notched Strap For King Seiko Vanac 5626 7250 Watch
The King Seiko Vanac 5626-7250 is a 1970s integrated-case automatic, and its faceted lugs won't take an ordinary strap. This order rebuilt it with a corner-notched Epsom strap, cut to the case and sized for a 7.5" – 8.0" (19 – 20 cm) wrist.

Why these choices
Vintage integrated cases like the Vanac were designed around one bracelet, so a straight strap leaves a gap at the lugs. We cut this as a corner-notched strap, shaped to the customer's measurements so the leather fills the case opening the way the original bracelet did.
Epsom is a good match for the job: its fine stamped grain is scratch-resistant and firm, so a notched edge stays crisp against the faceted lugs. Black keeps a two-tone 70s Seiko versatile. It sits in our Epsom and black strap ranges.

FAQ
Why does the King Seiko Vanac need a notched strap? Its integrated case is built around a fitted bracelet, so a standard strap won't sit flush at the lugs. A corner-notched strap cut to the case closes the gap.
Can you fit other vintage integrated watches? Yes. We cut notched straps to customer measurements for integrated-bracelet and vintage dress cases that standard straps can't fit.
Made to order — allow 2–3 weeks to delivery. Start a corner-notched strap or browse Epsom leather.
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. That's what a notched strap is for: the corners are cut away so the end seats cleanly against the case.
