Emmanuel, known as quattro, brings us an exclusive first look at Yosuke Sekiguchi's 2026 Primevère. This article delves into the independent watchmaker's latest creation, highlighting key design updates and inviting the community to weigh in on its aesthetic choices. Emmanuel's detailed post, complete with comparative images and historical context, provides an invaluable resource for collectors interested in Sekiguchi's evolving craftsmanship.











Yosuke Sekiguchi represents the contemporary generation of independent Japanese watchmakers who have gained recognition in the global horological community. The Primevère model showcases Sekiguchi's approach to classical watchmaking aesthetics, drawing from traditional design principles while establishing his distinct voice as an independent artisan. This piece reflects the broader movement of Japanese independents who have emerged as serious contenders in the haute horlogerie space.
The Primevère features a clean, classically proportioned case in yellow gold paired with a deep blue enamel dial that demonstrates technical proficiency in traditional dial crafts. The subsidiary seconds at 6 o'clock and the Arabic numeral hour markers create a balanced composition that emphasizes legibility and proportion. The manual-winding movement architecture aligns with Sekiguchi's focus on fundamental watchmaking principles rather than complex complications, allowing the execution quality to speak for itself.
As a piece from a contemporary independent maker, the Primevère occupies the emerging market segment for modern Japanese independents. The combination of traditional techniques with contemporary sensibilities positions this watch within the broader collector interest in discovering new voices in independent watchmaking. The limited production scale typical of independent makers suggests potential collectibility, though the long-term market position will depend on Sekiguchi's continued development as a recognized name in the independent watchmaking community.
Of course, I would prefer white metal.😆 I think I prefer the Roman numerals in this case. Seeing the numbers upside down at the bottom would drive me crazy.🤪 For a Japanese brand, I’m surprised by the case diameter. I would expect perhaps 36mm - 38mm.🤔 Thanks for sharing these, Emmanuel!🥂
for over 25 years and considers himself a Swiss watchmaker: I don’t know if it explains the case diameter, but he told me this very clearly 😅! Yes, Roman numerals might be more appropriate here. Thanks for sharing your thoughts! Best, Emmanuel
Unfortunately when I met him and considered acquiring one of his watches the prices had increased by 20k because he was more and more sought after… Roman might be the way to go, indeed. Best, Emmanuel
and his hand-finishing. Very exquisitely done.
