Custom Open Ended Straps for Tissot Heritage Porto. 31.1 mm Quartz T128.509.1603200

The Tissot Heritage Porto is a cushion-cased dress watch whose fixed bars a standard strap can't thread onto. The answer is an open-ended strap. We made one in black Swift, 16 mm to fit the case with a 75/125 mm length.

Why these choices

The Porto's case keeps its bars fixed, so a closed strap end can't get around them. An open-ended strap has an open tip that feeds under the bar and fastens, which is what lets leather go on a watch built for a pass-through band.

Swift is a good match here: smooth, supple black calfskin that suits the Porto's dress character and keeps a clean open end. The 16 mm width is narrow, and we cut the 75/125 mm length to the wearer's wrist. See it in our Swift and black strap collections — all made to order.

FAQ

What is an open-ended strap? It's a strap with an open tip that feeds under a fixed bar, so it fits watches like the Heritage Porto where the bars can't be removed.

Can you make it in a narrow 16 mm width? Yes. We cut to your exact lug width, including narrow dress sizes, and to your wrist length.
