Ok here they are in the sorry state they're in.

The strap for the FM is peeled off at the top
The Corum winding knob comes right off once it's unscrewed, yes, it can be removed with the needle, the watch still works though. But I cannot adjust the time.
The Suunto Observer this is the second resin strap which was eaten alive by my sweat, thinking to get a steel or leather replacement.
the Breitling has multiple scar wounds and both chrono buttons are sealed, caked in.
Haha.. any good advice to prevent recurrence of above symptoms will be much appreciated bros.
p/s my apologies to the mod about putting the shop's name.
