Black Alran goat corner-notched strap for the Seiko Astron Nexter SBXY067

Notched Strap for the Seiko Astron Nexter

The Seiko Astron Nexter SBXY067 ships on an integrated bracelet that tapers hard from the case, so a standard strap won't fit: there is no normal lug gap and a straight strap end would leave a visible step. This build is a corner-notched strap cut to the case in black Alran goat leather, tapered to follow the bracelet's line.

Why these choices

Corner-notched is the pattern for integrated cases like the Astron, the same approach used on a Cartier Santos. The strap end is cut with notches at the corners (measured A, B and C) so it tucks into the case opening where the bracelet's end link sat. We cut to the customer's figures: 24mm wide, 11mm deep, with a 3.5mm corner.

The customer asked us to copy the bracelet's aggressive taper, dropping from 24mm at the case to 18mm at the clasp. Matching that line is what makes a strap look like it belongs on the watch rather than added to it, so we kept the same rate of taper through the strap.

Black Alran goat is a fine-grained, supple leather, softer than cowhide, with a tight grain that holds a clean edge. On a modern sport-dress Seiko it reads sharp without the bulk a padded calf strap would add.

FAQ

Can you make a notched strap for the Seiko Astron? Yes. We build corner-notched straps to your case measurements (A/B/C) and can match the bracelet's taper, as we did here from 24mm to 18mm.

Can a notched strap take a deployant clasp? Yes. A deployant can be fitted to a notched strap; tell us when you order and we'll size the tip end for it.
