When the article on the new Nivada Grenchen Antarctic Erotic model was published on April 1, many perceived it as a joke.
Despite the images being of significantly higher quality than typical AI renders, readers assumed it was a carefully crafted prank by Guillaume Laidet and his team. However, I can confirm: the watch is real, and it is on my wrist as I write this text.
History and Significance of the Antarctic Model from Nivada
Antarctic is one of Nivada's most sought-after models. Over the years, I have tested several versions. The new Antarctic Erotic looks almost identical to previous versions on the surface, but the difference becomes apparent when you take the watch off and examine it from the back.
During last year's Windup event in New York, Guillaume invited me and some colleagues aside and said, "Come, I want to show you something. And I would like to record your reaction." If you're as familiar with the founder of Nivada Grenchen as I am, you know this can only mean a few things, most of which are quite unusual. At that time, the watch's animation was just a CAD model, but even that gave us an understanding of its essence.
While some brands create gold watches for their centennials and others launch new lines, Nivada presented the watch world with a model featuring penguins "doing it" on the case back, right above the movement. Yes, the Antarctic Erotic, which from the front looks like a regular three-hand watch, reveals a completely different view from the back.

History of Erotic Watches: From Classics to Modernity
Erotic watches are not new. This tradition dates back to the Swiss and French watchmaking of the 18th century, when wealthy collectors ordered pocket watches with secret animated scenes that opened with a repeater or button. Masters like Jaquet-Droz and other Swiss ateliers were the first to create such pieces for personal pleasure, combining serious craftsmanship with personal and taboo content.
By the end of the 20th century, the genre experienced a revival: Blancpain produced minute repeaters with engraved automatons on case backs, Ulysse Nardin introduced animated figures on dials, Jacob & Co. and Richard Mille made bold luxury statements. Nivada, in turn, chose a completely different path.

Main Features of the Antarctic Erotic Model
Before we get to the penguins, let's look at the watch itself. Nivada released six versions of the Antarctic Erotic. I have the brown version on my wrist. Other available dial colors include salmon, eggshell, "tuxedo," white, and black. The case is made of 316L stainless steel, with a diameter of 38 mm, a lug-to-lug length of 45 mm, and a thickness of 12.45 mm.
While it may not be the thinnest manually wound watch, the thickness is due to the double-domed sapphire crystal in the front and a flat sapphire crystal on the case back. The moderate size ensures the watch fits comfortably on both large and slender wrists. The lug width is a universal 20 mm, and the choice of straps and bracelets includes leather, rubber, and two types of steel bracelets. My model features a brown Racing-style strap that pairs beautifully with the dial.

Dial with a Vintage Touch
Some dial options look modern, but the brown tone of this model refers to a vintage aesthetic. Large, long applied indices, numerals at the 3, 6, and 9 o'clock positions, and an inverted triangle at 12 create a recognizable nod to one specific classic model, which I have no complaints about. The dial layout is simple, text is minimal: under the 12 o'clock mark is "Nivada Grenchen," below is "Antarctic Erotic," and under the second scale at 6 o'clock is "Swiss Made." The hands and hour markers are coated in beige lume (some might call this "faux patina"), which harmonizes perfectly with the warm dial tone.

Movement with Unique Animation
Turn the watch over and look at the movement. About a third of the caliber is hidden behind the animation. The heart of the Nivada Antarctic Erotic is the Soprod P054 movement - Swiss, manually wound, with 17 jewels, no date, and a frequency of 28,800 vibrations per hour. It is not the most complex or powerful movement, but it is reliable and functional. The power reserve is 42 hours, and the case withstands pressure up to 10 atmospheres (100 meters), making the watch suitable for daily wear. But the main feature is the animation located above the movement.

The penguin, traditionally depicted on the case back of the model as a gold medallion, is the logo of the Antarctic family. For the anniversary version, Nivada decided to add a "twist." Honestly, I did not expect such a turn, but the result does not bother me. It sounds provocative, but in reality, it is much calmer. Push the crown and wind the movement - you will see two penguins, one after the other, and the rear bird "jumps" up and down, imitating the mating process. Anyone familiar with erotic watches can confirm: this is the most restrained and least vulgar version of all.

Conclusion and Purchase Recommendations
The Nivada Antarctic Erotic is available in six versions, with the starting price of €1600 on a strap. Choosing a steel bracelet (flat links or "rice grains") increases the price to €1805. Although it is not the most budget-friendly option, it aligns with the brand's overall strategy and remains accessible. You get a reliable watch with an original "feature" at a competitive price. Personally, I liked the model on the brown Racing-style leather strap the most, but it is worth considering purchasing a steel bracelet for an additional cost. As of this publication, the pre-order for the Antarctic Erotic has been open for just over a day. If this model interests you, we recommend placing an order as soon as possible.
