Review: Fits My Longines HydroConquest Perfectly - Quality rubber strap with premium hardware. Perfect fit and looks just like the stock strap that comes with the watch. My only complaint is the sharpness of the buckle corners. I sanded them down with success and no damage. I’m very pleased with the strap despite. Saved a ton of money on the same look! Can’t go wrong.
Review: Doesn’t fit Tag Aquaracer - I could not get this bracelet to fit without cutting it with a razor, it doesn’t look as good as I would like now, so wouldn’t recommend ordering for a Tag Heuer Aquaracer. I did get it to fit but not without damaging the bracelet.
