World premiere: mechanical watch as a self-portrait
Now, as the Joker Selfie project is revealed to the public, the idea for this timepiece seems self-evident. However, the fact is that before Konstantin Chaykin no watchmaker in the world had conceived and made a mechanical watch as a self-portrait.

That is not to say it is about simply putting his own image on the dial. This easiest option was not even considered by Konstantin Chaykin as it isn't his style to simplify the tasks that he sets himself. According to Chaykin the best recipe for a really captivating watch is that the master himself should like the watch he created – in that case, there will certainly be at least a few discerning connoisseurs of watchmaking, from the more than seven billion people living on our planet, who like this watch, created as the pinnacle of watchmaking craft and art vision.

So, what is the recipe for the self-portrait watch by Chaykin? First, he takes the Joker watch with its characteristic dial, designed as a joker's face where the elements of the face have functional roles – hour and minute subdials form the eyes and the moon phase indicator forms the Joker's famous smile. Then, he changes the color scheme of the dial ever so slightly to reveal his own facial features – just a hint, no more. That's how the new watch acquired the name "Selfie" – Joker Selfie Only Watch-2019 Piece Unique. Afterwards Chaykin takes a watchmaker's loupe – the traditional tool of watchmakers for centuries – and sets it above the right eye of the Joker Selfie.

Finally, as a touch of his branded spice he adds a bit of ingenuity, mixed in equal parts with his secret ingredient – the new secret function of the day of the week indicator, created by Konstantin Chaykin especially for this watch. It shows the days as joker-style emojis. You can find more information of how the secret function operates here.
10 facts about self-portraits
Professional art analysts subdivide the genre of self-portrait into several areas. According to widely accepted classifications, the Joker Selfie watch clearly falls under the 'professional' category. In painting, this means that the artist paints himself, for example, on a canvas, together with his brushes and a palette. Konstantin Chaykin depicts himself with a watchmaker's magnifying loupe...

Caravaggio and Goliath
There is a well-founded opinion that in the painting "David with the Head of Goliath" (painted around 1605) the great Italian artist Caravaggio depicted himself in the severed head of Goliath.

This is supported by the obvious similarity of this image with the portrait of Caravaggio painted by the Italian graphic artist Ottavio Leoni. Caravaggio often painted self-portraits as a secondary character in multi-figure compositions.

As Christ
Albrecht Dürer, one of the great masters of painting and prints, created several self-portraits including the famous "Self-Portrait with Fur-Trimmed Robe" (circa 1500), where he is believed to have presented himself as Christ.

This was undoubtedly a bold move for the artist. Incidentally, Dürer is thought to be the first European artist to write an autobiography.

As a saint or a tempter
In 1889, Paul Gauguin portrayed himself in "Self-portrait with a halo and a snake", both as a saint with a halo, and as a tempter with serpent in hand and a branch with apples (the forbidden fruit). In total Paul Gauguin created more than forty self-portraits.

While dreaming
Marc Chagall wrote in his book "My Life" that the idea of painting "Self Portrait with Muse (Dream)" (1917) came to him while he was dreaming.

Self-portrait or not?
"La Gioconda" or the "Mona Lisa" by Leonardo da Vinci is one of the most famous paintings in the world. Every year millions of people come to see it in the Louvre in Paris.

The question of who is depicted in the painting has remained unclear over the centuries. One version is that "Mona Lisa" is a surreptitious self-portrait.

The most expensive self-portrait
In 1998 Van Gogh's "Portrait of the Artist Without his Beard" (1889), believed to be the last self-portrait of the artist, was sold at Christie's New York for $71.5 million, becoming one of the most expensive self-portraits ever sold.

Stolen and recovered
"Self-portrait with Beret and Gathered Shirt" (1630) by Rembrandt (estimated value $37m) was stolen from the National Museum in Stockholm in an armed robbery in December 2000. Fortunately, it was recovered in 2005.

A recognizable moustache!
Not surprisingly, Salvador Dalí had an unconventional approach to depicting himself. He painted his own image in "Soft Self-Portrait With Grilled Bacon" (1941) in a soft organic manner typical for his art. There is no doubt about whether Dalí painted it or not thanks to the clearly visible upturned mustache. Actually, he probably could have painted just his legendary moustache!

Self-portrait in a mirror
Jan van Eyck, the famous painter and an innovator of the oil painting technique, is one of the earliest masters of the self-portrait. In his painting "The Arnolfini Portrait" (1434), believed to be the first double portrait in European painting, he put into the center of the composition the image of a convex mirror. A closer look at the mirror reveals a few reflected characters, with one of them thought to be Jan van Eyck himself.

Self-portrait of the Last Judgment
In "The Last Judgment", a fresco painted by Michelangelo in the Sistine Chapel, the noteworthy figure of St. Bartholomew, who is painted holding his own skin, may be seen. There are suggestions that in the outlines of the skin, which the apostle holds in his hand, Michelangelo depicted himself.
