This is a Hamilton Air Race Khaki GMT H77665673.
I purchased the crocodile-embossed strap model, but soon became concerned about sweat stains, so I bought a rubber band and have been using that.
As I have thin wrists, I have added extra holes to both bands, so please check the photos.
The watch itself has some minor scratches.
The leather band is clean because it was only used for a short trial period.
The rubber band doesn't look as dirty in the photos as it actually is.
Since I don't think I'll have a chance to use it, I'll include the band replacement tools in the set.
