A two-tone watch does not mean just any two tones. It means a white metal (usually steel), mixed with gold, either rose or yellow. Two-tone was originally introduced as a way of making watches, which were once all gold, more accessible, by mixing in steel. The look was prevalent in the early ’90s, as was quartz, before watches began their return toward mechanical movements and their ascent to luxury status. Today, the look is vintage and stylish, and far more interesting than the two-tone watches of the past. The white tone is still achieved with steel, but is also being done with titanium – so two-tone is no longer necessarily done as a cost-effective option. The gold tone, traditionally yellow, is now commonly rose gold. The advantage of a two-tone look is that it is more casual than an all gold watch and dressier than all-steel.
