Description

The Jaeger-LeCoultre Master Control Calendar Q4148421 debuted in 2025. It features a stainless steel case measuring 40mm in diameter and 10.95mm in height, paired with a silvered grey sunray dial and dauphine-style hands. The calendar layout includes day and month apertures below 12 o’clock, a central date hand with a jumping mechanism that skips the 16th to avoid obscuring the moon phase aperture at 6 o’clock. This watch is powered by the automatic 866AA, which offers hours, minutes, moon phase, full calendar, and central date with jumping hand. It has a power reserve of 70 hours and beats at a frequency of 28,800 vph. The movement is visible through a sapphire crystal case back. The watch is delivered with a light brown calfskin strap and an additional black alligator leather strap, both equipped with a stainless steel folding clasp.

Como apasionado a este mundo relojero, desde hace muchos años, de vez en cuando me sorprenden empresas como Chrono 10:10. Es el primer reloj que les compro y no será el último. Trato exquisito, calidad magnífica ( Breguet Tradition ) y en 24 horas lo he recibido ( vivo en España ). Por supuesto, voy a recomendaros a todos mis amigos, con mi misma afición. Felicidades por vuestro buen hacer.

IWC Grande Complication Portuguese

Einwandfreie unkomplizeirte Abwicklung. Alle Angaben zur Uhr waren kompetent und richtig. Obwohl die Uhr ohne Original-Papiere angeboten wurde, wurden die Papiere ohne Mehrpreis beigefügt, nachdem der ursprüngliche Eigentümer diese wiedergefunden hatte. Die Uhr wurde durch einen Booten pünktlich überbracht und es wurden noch einige nette Assesoires beigefügt. Auch dasOriginal Lederarmband war in korekter Größe beigefügt. Sehr guter Service, ich werde sicher noch die Ein oder Andere Uhr bei Chrono 10:10 kaufen.

Perfekte Abwicklung, sehr gut verpackt, dazu zwei nette Beigaben - eine kleine, hochwertige Reisebox und ein Kugelschreiber. Wirklich beispielhaft. Der Händler ist definitiv empfehlenswert.
