Altanus Master Gran Data VALJOUX Chrono Silver and Gold Silver Dial 43mm
Altanus Master Gran Data Automatic Collection
Classical Swiss watchmaking with the everyday practicality of an automatic day-and-date display.
The Altanus Master Gran Data Automatic Collection combines traditional round-case proportions with a substantial 43mm presence and the understated elegance that defines the wider Master family.
At its heart is the proven Swiss VALJOUX 7750 automatic Chronograph movement, displaying both the day and date alongside the hours, minutes and seconds.
Anti-reflective sapphire crystal protects the dial, while an exhibition caseback reveals the mechanical movement beneath. Water resistance is rated to 5 ATM / 50 metres.
The collection offers a broad choice of finishes, including stainless steel, steel-and-gold and full-gold versions, together with handmade leather straps or seven-row steel bracelets and a selection of silver, black and blue dials.
Why buy it?
Because the Master Gran Data combines useful everyday functionality with traditional Swiss mechanical watchmaking.
A refined automatic watch with genuine presence, classical styling and the convenience of seeing both the day and date at a glance.
