Leather-style watch band with folded thinned seam
A wristband made from two or more flexible band portions whose ends are locally thinned, stacked, affixed with a coupling component, and folded onto themselves to form a folded seam. The construction is intended for wearable electronic devices such as smartwatches and is sold to consumers who buy replacement or OEM watch bands.
(57) What the patent covered
This write-up was generated by AI from the patent's text and may contain mistakes, so check it against the original patent before relying on it.
The main independent claim requires two distinct band materials each having a thinned portion at an end, a coupling component that couples the two ends together, and each thinned portion folded onto itself after being coupled. The claim covers the arrangement of thinned end regions, their adjacency and affixation by a coupling component, and the folding of those thinned portions onto themselves.
Distinguishing feature: Locally thinning each band end, affixing the thinned ends with a coupling component, and folding each thinned portion onto itself to form a seam.
Novelty 3/5. This is a mechanical refinement of common multi-layer watch-band seams; thinning and folding the end layers before affixing is a specific assembly detail not universal in ordinary bands.
Manufacturing
Cut band blanks; form thinned end regions by skiving or milling; stack thinned ends; affix with adhesive and a metal coupling component (stamped or machined), then fold the thinned portions onto themselves and perform final stitching or edge finishing.
Materials: Leather or leather-like polymer (PU), fabric or textile inner lining (likely woven), stamped or machined metal coupling component (steel or stainless), adhesive (contact or structural).
Manufacturability 4/5. Skiving (leather or polymer) and stamping/machining of a small metal coupling part plus 3–6 assembly steps (adhesive application, folding, optional stitching); standard for watch-band suppliers.

Before manufacturing
No related continuation or divisional patents in force were found. Design patents, trademarks and unrelated patents may still cover the product.
Claims describe a particular sequence and structure (thinned ends affixed and folded); the patent is lapsed but the specification is specific about skiving/thinning and folding steps, which may limit similarity to generic bands.
About 1.5% of lapsed patents are later revived by their owners. This page is a research lead, not legal advice. Obtain a freedom-to-operate opinion before manufacturing.
