Louis Erard lists reference 85248AA03.BSA02 as a 178-piece limited edition. Its current product page shows CHF 4,250 excluding tax; price and delivery details are a live listing snapshot accessed October 8, 2026.
What is the Louis Erard x GoS?
It is a mechanical regulator watch created by Swiss watchmaker Louis Erard and Swedish independent watch brand GoS. In a regulator layout, the time indications are separated rather than arranged as a conventional set of centrally mounted hour, minute and seconds hands. On this model, the display combines rhodium-plated chapter and hour-counter rings with blue signature GoS hands, set against a Damascus steel lower dial plate.
Louis Erard lists the watch under reference 85248AA03.BSA02 and describes the edition as limited to 178 pieces. That is the stated edition size, not a report of how many have sold or been delivered. Louis Erard’s product listing is the source for the reference, edition and specifications.
Who made the Damascus steel dial?
Louis Erard credits blacksmith Conny Persson and Patrik Sjögren of GoS with making the Damascus steel lower plate; Sjögren designed the dial. The dial’s other listed details include rhodium-plated, circular-satin-finished chapter and hour-counter rings with diamond-polished angles, plus the blue GoS hands.

How the collaboration came together
GoS dates the first discussion with Louis Erard’s Manuel Emch to Dubai Watch Week in 2021. The partners prototyped the workflow in 2023, began production in 2024, announced the collaboration in March 2025 and premiered it at Watches & Wonders 2025. GoS also describes the project as a return to its Damascus steel roots and says scaling production and finishing beyond its usual quantities was a challenge. Its account is available in GoS’s collaboration announcement.
