Have you ever wondered for a moment what is actually defined as a smartwatch?

Well, most will associate a smartwatch as a wristwatch with an electronic screen display that not only displays the time but comes with other added features, most times loosely marketed as lifestyle enhancing apps but whether these genuinely improve your life or are must-haves is debatable.

In a Deloitte Watch Industry Study conducted in 2015, some 61% of the respondents ticked off long battery life as an important feature in a smartwatch.

For those thinking of buying one, do take note of one advice offered by PC Magazine: “Buy it for looks, don’t buy it for life.” We fully agree.

As the styles and technologies used in smartwatches will continually evolve, one cannot expect to wear the same smartwatch for years. After all, what is considered a new smartwatch today is old tomorrow.

For horological purists, “smartwatches” are typically mechanical timekeeping mechanisms that tell more than the time; they provide horological information such as calendar indications, the age of the moon phases and even audio time-telling experiences through striking mechanisms known as repeaters.

Vacheron Constantin’s Overseas ultra-thin perpetual calendar is a smartwatch. It is a mechanical masterpiece of the human spirit and is rightfully “smart”. It is not a fashion item lasting a season or two, and can operate for years and offer accurate horological information thanks to its self-winding mechanism with no need whatsoever for any worry over “battery life”.

A mechanical smartwatch can also offer “connectivity” – what we would define as the emotional connection leading to its demand and the eventual purchase. In other words, the mechanical smartwatch can offer both emotional and functional satisfaction… for life.
