Dive Watch

Not all dive computers are easy to see the time, and sometimes we just want something to simply tell us what the time is without pressing any buttons - as well as one we can wear in and out the water. We love Abingdon watches for a number of reasons. Number 1 being it is founded by kick-ass GTS member Abingdon who is a pilot and adventurer, she designs these watches for women in sports usually dominated by men. Her passion for female empowerment and diving go hand in hand helping her design these beautiful dive watches. Good down to 660ft and beautifully built with it’s Mother-of-Pearl dial and lightweight titanium case it's an absolute beauty and compliments our dive kit so well. Abingdon dive watches offer GTS membership holders 10% off their whole collection - saving you a lot of $$!
