This is a discussion on What is your most reliable watch within the Watches forums, part of the Everything But Cigars category; Everyone knows about Rolex, Tag and some of the other top watches on the market but if you were looking ...
I have three watches, an Omega Speedmaster, a Festina Chronograph and a Swatch Irony. All are extremely reliable but if you are looking for a reliabale watch that looks good and is real value for money, have a look at the Swatch Irony. I've attached a link to images. Some are a bit out there but others are also very classy/sporty looking. Mine is similar to the last one in the second line.
If you are looking for reliable, ie keeps good time, then I would stick to a quartz watch. There are many affordable quartz watches and they keep better time than my Rolex, which loses -2 sec a day. I'd start looking at Seiko or Citizens
I have an esquire Daytona (looks like a rolie but a tenth the price), A Klaus Kobec Sport Two tone and A Rolex Date Just with a Diamond bezel.
The Rolex is the nices but not surprisingly, doesn't keep the best time. But I like it.
