We zijn er trots op Ultra-Quartz te kunnen aanbieden: het eerste Cybernetic Quartz-Watch. Een horologische legende: het eerste quartz-gereguleerde (cybernetische) horloge -- Longines Ultra-Quartz cal6512. Een maand eerder presenteerde iedereen anders Longines de Ultra-Quartz -- in feite een stemvork-horloge dat wordt gecorrigeerd door een quartz (cybernetisch). Dit alles werd gerealiseerd door handgesoldeerde transistors en zonder een geïntegreerd circuit. De wijzerplaat vertoont wat patina rond 3 en 9 uur door oxidatie, maar het uurwerk is schoon (geen batterijlekkage) en werkt, met de gebruikelijke onnauwkeurigheden van een Ultra-Quartz. De kast is in scherpe en ongepolijste staat. Het is waarschijnlijk nooit gedragen. We presenteren het horloge met een op maat gemaakte grijze band in Pilot-design en ook de originele en duidelijk ongebruikte stalen armband. Longines Heritage bevestigde dat dit horloge de originele kast en het uurwerk is die in 1971 werden gemaakt.

We zijn er trots op dat we AP Cobra: Diamond Dial kunnen aanbieden. WAAROM WE ER DOL OP ZIJN: Is er ooit een meer geïntegreerd armbandhorloge van AP geweest met een vergelijkbaar aantal facetten? Nee. Daarnaast was het destijds een van hun topmodellen. Mid-Size Cobra van Audemars Piguet in uitstekende staat -- kast en band in fantastische vorm en staat en voor onze ogen ongepolijst, zoals blijkt uit de intacte oppervlakteafwerking. Alleen de wijzerplaat heeft wat tekenen van ouderdom en oxidatie, vooral rond de aangebrachte diamanten indexen. Hier hebben we een medium cobra met een spectaculaire rijstband, gemaakt in de vroege jaren 1980 volgens onze boeken. Dezelfde verwijzing werd gemaakt sinds de vroege jaren 1970 in verschillende modellen en destijds een van de onbetwiste topmodellen in het portfolio van AP -- geprijsd op meer dan CHF10'000 meer dan 50 jaar geleden, terwijl de AP5402 rond de CHF4'000 in staal kwam.

Length can be personalized ******************************** The Sonora Sunrise, also known as Sonora Sunset, Sonora Sunrose, or Chrysocolla Cuprite, is a semi-precious stone with fascinating origins. Its name, Sonora, pays homage to the Mexican state where it is extracted, a region rich in history and traditions. This stone, with its shades of red, orange, and blue, evokes the sunrise or sunset, hence its evocative names. Its colors are reminiscent of desert landscapes during sunrise or sunset, with tones that can be very vivid and intense between the sunlight, the blue sky, and the green of the cacti. Sonora Sunrise is quite an odd stone, especially when referring to it's energies. Oddly enough, this copper oxide mineral helps one communicate love, change, manifestation, and inner vitality all at once...
