Any watch with moving parts will suffer more than a digital watch. Many will site the toughness of diving watches but those watches are tough in a very specific environment i.e. in the ocean. On a bike or many other sports, you want to be able to see the time or other information quickly, really quickly, if you are travelling at speed. A digital watch has a big digits to read, watches with hands don't. Plus many watches with hands if they have extra features are accessed through the crown. A digital watch you just hit one button to get the function you want. Another advantage of a digital g-shock is you can set it to auto illuminate. Get a g-shock they range from cheap to bling. I particulary like the solar versions.
In my experience people buy a fancy watch tiso t-touch, garmin, suunto, but when they get smashed, break you see old hands in outdoor profession revert to a solid affordable digital watch G-shock dw5600 or similar. Look at what the professions use, outdoor instructors, military, police, basic digital. My previous g-shock solar lasted 20years, still works, I gave it to my dad, then bought another G-shock. A watch which you never have to consider, used it climbing, downhill biking, kayaking, roofing, demolition, building work, just does not care. Yet friends around me, "oh i just need to take my expensive watch off" before doing x, y or z.
