Buy yourself a cheap watch that tells the time, maybe with a stop watch in it if your eyesight is any good - or a fake if you need the bling - and spend the change on fuel.
I know times are hard, but if my company starts asking me to pay for fuel, I am definitely looking for a new job!!!!
However, you really cant go wrong with a Sinn 356. Good VFM nice design, doesn't stand out or bling blind anyone, has a day and date, which, due to my working rosters, I never know the day without it, excellent lume, so i can see the time in bed and know I still have 3 hours left to sleep, and it has a chronograph stopwatch for when I get bored and have run out of buttons to push elsewhere.
