One of the top contenders for the title of \\most well-known square watch of all time\\ is, without doubt, TAG Heuer\\s Monaco (the other top contender is right below). Made famous on the wrist of Steve McQueen, Monaco embodies the style of the \\60s and \\70s owing to its softly flared case and funky dial. We happen to think as well that TAG Heuer\\s newest version might be the best yet. brYour Favorable Bell Ross Horolum brYou can\\t make a list of square watches without Bell Ross. First released in 2005, their instantly identifiable instrument replica watches cribbed their looks from the dash instruments of fighter jets. Recently though, Bell Ross has been pushing in different directions, as you can see from the stealthy matt grey-on-grey Horolum.
