Black Swift Leather Custom Notched Strap For Seiko 7A38-7029 Watch
Share
The Seiko 7A38-7029 is a 1980s analog quartz chronograph with an integrated-style case, and its owner wanted a clean black leather strap that sat flush at the lugs instead of standing off them. We cut a black Swift notched strap to the customer's measurements for a 7.0" – 7.5" (18 – 19 cm) wrist.

Why these choices
Swift is a smooth calfskin that takes color deeply and stays supple, so it reads clean and modern on an 80s sports chronograph without the stiffness of a structured leather. Black keeps it versatile. See more in our Swift and black strap ranges.
The 7A38 case needs the strap to sit flush at the lugs, so we cut this as a notched strap to the customer's own measurements, then sized the length to a 7.0" – 7.5" wrist. Every strap is made to order to fit the case you have.

FAQ
Can you make a notched strap for a vintage Seiko chronograph? Yes. We cut notched straps to your measurements so the leather seats flush against integrated-style cases like the 7A38.
How do I measure for a notched strap? We recommend having a jeweler measure the case opening; we cut to those figures. The strap length calculator handles the wrist length.
