Chopard Ferdinand Berthoud FB1RES4 Remontoire

Key Points from the Discussion

• The COSC certification for Ferdinand Berthoud watches, particularly those with complex mechanisms like the remontoire and fusee-chain, is a significant differentiator. While COSC is often associated with simpler sports watches, Berthoud's timepieces not only pass but often exceed these chronometric standards, with individual performance stats provided to the owner.
• Despite the impressive chronometric performance, there is a perceived lack of clarity in Ferdinand Berthoud's communication regarding their COSC certification, leading to some confusion about whether they merely satisfy or truly surpass the ISO 3159 criteria.
• The FB1RES4's 44mm octagonal case, while large, is made more wearable by the absence of traditional lugs, which effectively reduces the lug-to-lug dimension compared to many smaller watches with conventional designs.
• Some collectors express a desire for Ferdinand Berthoud to produce smaller case sizes, especially for models without the fusee-and-chain complication, which inherently requires more space.
• The watch's aesthetic combines a 'steampunk' vibe with classic horology, creating a bold visual presence that may require some adjustment for wearers.
• The customization option for the FB1RES4, allowing customers to choose case shape, material, and dial color within the limited run of 38 movements, highlights the brand's bespoke approach.
