On Wednesday, March 11, 2026, on the first fruit day according to the biodynamic calendar, an exceptional evening took place at the Prague wine bar Lot of Wine, which, under the auspices of Top Class magazine, brought together two worlds – the world of great wines and the world of fine mechanics. In the historic setting of Týn, just a few steps from the Prague Astronomical Clock, lovers of wine, watches and astronomy gathered to experience an evening inspired by the phases of the Moon and their influence on both wine and time.
The central theme of the evening was a tasting of the legendary wines of Château Le Puy, a family winery from the Bordeaux region whose history dates back to the 17th century. Domaine Le Puy is renowned for its exceptionally sensitive approach to nature – the vineyards are cultivated according to biodynamic principles, without chemicals and with deep respect for the natural rhythms of the earth. Here, the Moon plays a crucial role.
The winemakers plan vineyard work, harvest and certain phases of vinification according to the lunar calendar, as they believe the movement of the Moon influences both the vitality of the vines and the character of the resulting wine.
Throughout the evening, guests tasted wines that embody not only the terroir of Bordeaux, but also a philosophy of working with time and nature. The tasting, guided by sommelier Martin Kudrnovský from Sklenka Francie, gradually revealed how the structure, aroma and energy of the wines change depending on lunar cycles – and how the Moon thus becomes a quiet partner in the art of winemaking.
The theme of lunar cycles was not reflected only in the glasses. Alongside the tasting, a diverse collection of watches was presented, all displaying the moonphase – one of the most poetic complications in watchmaking. Watches from Union Glashütte, Mühle Glashütte, Longines, Frederique Constant and MeisterSinger were showcased on the tables, their mechanical calendars and lunar indications recalling the ancient and very close connection between astronomy and the measurement of time.
The highlight of the evening, however, was the presence of a remarkable guest – Dutch watchmaker and constructor Pim Koeslag, who personally designed all in-house movements for Ateliers deMonaco, Alpina and Frederique Constant, and who today stands behind the technical development of complications for the brand Christiaan van der Klaauw.
This independent Dutch manufacture is the only watch brand in the world dedicated exclusively to astronomical complications. Its watches are capable of displaying not only the phases of the Moon, but also the movement of the planets and even a complete mechanical planetarium.
Pim Koeslag brought nine of these fascinating haute horlogerie timepieces to Prague – miniature orreries and planetariums whose construction requires extraordinary technical precision. Each of these movements is the result of thousands of hours of development and production, representing a unique combination of science, craftsmanship and the poetry of the universe.
The symbolism of the location thus gained an unexpected depth. Just a few steps from the Prague Astronomical Clock, one of the oldest astronomical clocks in the world, an evening unfolded that reminded guests that humanity’s fascination with time, the stars and the movement of celestial bodies is still very much alive.
The evening at Lot of Wine was therefore not merely a tasting or a watch presentation. It was rather a quiet and very private celebration of time – time that flows in the rhythm of the Moon, matures in the vineyards of Bordeaux, and at the same time is measured with microscopic precision in the mechanical hearts of watches.
