Louis Erard and Konstantin Chaykin Relaunch the Unfrogettable in Turquoise and Brown

Independent watchmaker Louis Erard and Russian master watchmaker Konstantin Chaykin unveil two new versions of their Unfrogettable, limited to 178 pieces each and priced at CHF 4,500 excluding tax.

Louis Erard and Konstantin Chaykin are extending their collaboration with two new versions of the Unfrogettable, introduced on September 22, 2026. Following a highly successful first edition in green and purple at the end of 2025, the Frog Princess returns in two new colorways: a Turquoise version and a Brown version, each limited to 178 pieces.

The Unfrogettable is built on a concept as precise as it is unique: a horizontal regulator display reinterpreted to form the face of a frog. The hours are indicated by a rotating disc at 9 o'clock, the seconds by a second disc at 3 o'clock, and a central arrow-shaped hand sweeps the minutes like a tongue. These two discs, which form the character's eyes, literally bring the dial to life as time passes. The crown is deliberately shaped like a royal crown, an instantly recognizable visual signature of the model.

The Turquoise version features a light blue-green grained dial, framed by dark blue-green and purple details. A two-tone minute track surrounds the dial, and the names of both brands are joined by a heart in the purple segment. The crown is made of polished titanium. The Brown version takes a warmer approach with a dark brown grained background and 5N PVD-treated accents on the crown, eyes, and minute hand. Both models share touches of green Super-LumiNova on the eyes and the tip of the hand to ensure legibility at night.

The case is identical for both variants: 40 mm in diameter and 12.45 mm thick, crafted from grade 5 titanium, a material already used for the original edition. The grained finish of the dial mimics the rough texture of frog skin. The movement is an automatic Sellita SW266-1, beating at 28,800 vibrations per hour, featuring 31 jewels and offering approximately 38 hours of power reserve. The oscillating weight is openworked and lacquered black in Louis Erard's signature colors.

The strap also deserves attention. Both versions come on Himeji Kurozan leather, a Japanese leather traditionally associated with samurai armor, naturally tanned, hand-rubbed, and finished with Urushi lacquer. The Turquoise version stands out with purple stitching and lining, while the Brown version opts for an all-black execution.

This new series illustrates the collaborative strategy that Louis Erard has been pursuing for several years with independent creators. By combining the aesthetic of Chaykin's Wristmons, inspired by Slavic mythology and Japanese symbolism, with the watchmaking expertise of the Swiss Jura, the two brands offer a timepiece that deliberately stands outside the usual codes of classic watchmaking, while maintaining an accessible price point in the character-driven mechanical watch segment. The price is set at CHF 4,500 excluding tax, identical to that of the original 2025 edition.
