This standard size watch strap came with my wife's Junghans watch, and is too large, so we purchased the same version in a small.
These sell for $120 in the US due to the tariffs, or $75 euros in Europe (see screen capture from the Junghans website).
Note, the website photos included with this ad are truer in terms of color than our photos, which make the strap look darker than it is. This is a light teal-blue color.
This strap is unused and will be shipped within 24 hours.
Short strap: 75mm
Long strap: 115mm
