Because I'm an idiot who cannot resist shiny new things, I have just upgraded to the new Garmin 935 and I'm therefore selling my 735XT. It a great little watch, with very accurate GPS and generally solid optical HRM. It's packed with all the latest features like live Strava segments and supports all the latest ConnectIQ apps. It's in great condition save for a small scratch on the top of the screen which is barely noticeable unless the screen is off or light is shining at the right angle. During training I never notice it (as you can see below, I had to turn the screen off and take a photo at an angle to get it to show up).
Comes fully boxed with original charging cable. Looking for £280 or make me an offer.
