Extra-Long Ostrich Strap for a Vintage Cyma Watch
Share
Most strap catalogs stop at sizes that fit a wrist of about 8.5 inches (216mm), and vintage watches make the problem worse: the original strap is long gone and the proportions are not modern. This order, shipped to Florida, put a vintage Cyma on a light brown ostrich leg strap cut to 115/170mm — about 11.2 inches (285mm) end to end.

Why these choices
The numbers tell most of the story. Our standard lengths start around 75/115mm, so this build adds roughly 95mm (3.7 in) of total strap — the long side alone, at 170mm (6.7 in), runs close to the full length of some standard straps. Extra-long builds cover wrists from 8.5 to 12 inches (216 to 305mm), territory most makers never enter. That range is the difference between a strap that merely closes and one that closes where it should — on the middle holes, with tail to spare.
The 14mm buckle width is the vintage half of the problem. Older pieces like this Cyma run slighter than modern sport watches, and narrow buckle hardware in that proportion has mostly left the catalogs. Finding 285mm of length and a 14mm buckle in one ready-made strap is effectively a dead end, so the strap has to be cut to the watch and the wrist rather than the other way around.
Light brown ostrich leg keeps the build in period character without turning it into costume. Against an aged dial, light brown wears warmer than black and dressier than tan, and the classic stainless buckle with regular tool-fit spring bars keeps every remaining decision conventional. On a strap this long, restraint is what stops the leather from becoming the whole show.
Frequently asked questions
Who makes an extra long strap for a vintage Cyma watch?
Custom makers, mostly. Off-the-shelf straps rarely pass 125mm on the long side. This build's 170mm (6.7 in) long side and 115mm (4.5 in) short side were cut to the customer's measurements, with the buckle end sized to the order's 14mm hardware.
What wrist size does a 115/170mm strap fit?
At roughly 285mm (11.2 in) of combined length, it sits in the upper half of our extra-long range, which is built for wrists from 8.5 to 12 inches (216 to 305mm). If you are between sizes, measure your wrist and order to the number rather than rounding down.
If standard lengths have never closed properly around your wrist, our extra-long watch straps are cut to measure in any leather we stock — browse the ostrich leather watch straps to see this one's family, including the light brown ostrich leg used here.
