An ultra slim watch is all the rage, especially for those of us with particularly slim wrists. It may just look like a slightly smaller version of the common wristwatch, but watchmaking technology has traveled quite the distance in order to slim these internal mechanisms, which can easily contain close to a hundred small parts, down to such compact sizes. German engineering has always been a cornerstone in the art of watchmaking, which is why it is no surprise that they introduced the world’s first “portable” mechanical clock as early as the 16th century. These portable clocks were not quite watches, but met the need for a timepiece that could be carried room to room. These smaller clocks, now generically referred to as “German table clocks,” were still pretty weighty and often the size of textbooks, so they weren’t exactly suitable as watches (though it wouldn’t have been much of a stretch considering 16th-century fashion trends.) That’s not to say that this wasn’t a huge step towards modern day watches, and it definitely lead the way for the slimming of mechanical clock mechanisms.
The advance in technology stalled for several years and then snowballed quickly at the end of the 18th century when watches were drastically slimmed down in order to meet the needs of fashion trends at the time, which were quickly moving away from 16th century puffy trousers and ruffled gowns and towards a more “clean cut” design that loosely resembles the modern day business suit. Every original watchmaking mastermind was hard at work producing thinner timepieces than ever before, finally leading way to the “knife pocket watch” by Jaeger-LeCoultre, which only measures up to an incredibly slim 1.38mm high.
Today, the wristwatch is an indispensable part of many daily lives, and the need for an ultra slim watch has not been replaced. Ultra slim watches for men are not unusual, though are a sort of specialty item all their own, so they can be a bit more onerous to find. This is not to understate the obvious need (by those with smaller wrists) and the evident style these ultra slim accessories bring to the table, which is why many of the top brands lend a hand at designing their own “slim” option. Not everyone agrees on what makes a watch “ultra slim,” so for our own purposes we’ve decided to stick with quality wristwatches that measure at or under the 10mm mark.
