I personally use a Casio Retro Digital watch W-59-1VQES like these:
I think I paid about £10-20 on Amazon for mine.
It has a stopwatch (not yet used in flight!) and it tells the time, and ... its waterproof... incase... well, just in case.
For engine start/stop times and approach times etc the seconds are not important so dont need a huge needle to tell me them.
For Nav timed legs ... well who after their PPL uses timed legs and DR anyway (apart from us CPL students!)
Infact over the years I have owned many of these - since my early childhood competition canoeing days... right up till now (36!)
I only ever wear a watch for flying and on RNLI Lifeboats cause the rest of the time Im slumped infront of a Mac Computer or have the iPhone near me.
If it tells the time. It will do for flying...
