very techie looking.. nice 

not cheap la.. if you convert it into how many boxes of chap-fan.. i think it can feed you for +1 month le, ngam bo?
btw, how often do you use the stop watch function?

i'm happy that you're proud of your chrono ownership..

hhmmnn.. i doubt that there will be much difference in accuracies when it comes to quartz-analogue vs. quartz digital. if both movement are set by the same maker..

it's still a quartz (and quartz are very accurate) the display (analogue vs digital) is just the output.. and i think your engtao quartz chrono is also those 0-jewel type, right? so friction is not a major issue? unless you want to factor in strong gravitational pull (high g) on those marker hands..?

moving parts in a watch create frictions.. and thereon, wear-&-tear from the frictions over time.

oil/lubricant can dry up over time (hence a periodic service is recommended)

so the best alternative for an mechanical watch (correction - some quartz do have jewels too) is to install jewels on those moving parts so that the metal(e.g brass) will rub against the jewels instead on another metal..

metal + jewel = less friction (relative speaking)

you don't need to worry as your casio don't have such problem.. it's like a electric prius that don't even need engine oil *lol*
