The Rolex Day-Date, launched in 1956 and touted by Rolex as the first chronometer wristwatch to spell out both the date and day of the week on its dial, has throughout its
long history been available only in gold cases. That tradition continues with five models launched in 2013, which have either an 18k yellow gold, 18k white gold, or 18k
Everose gold case and are available in different dial-strap combos.
The cases all measure 36 mm in diameter and are milled from a solid block of gold. These Rolex Day-Dates all have dials that match their leather straps and represent a
veritable rainbow of colors. There are five combinations available: green and cognac dials and straps on the watches with yellow-gold cases; blue or cherry on the watches
with white-gold cases; and chocolate on the watch with Everose gold case. (Everose gold is an exclusive, high-purity alloy made by Rolex that has a smattering of Safe
Trader App Review platinum in the mix.) There is also a more traditional version in Everose gold featuring a rhodium dial and black strap.
The cases, which measure a rather modest 36 mm in diameter, are milled from solid blocks of 18k gold and have fluted casebacks hermetically screwed down with special tools
used exclusively by Rolex watchmakers. The screw-down crown is fitted with Rolex’s Twinlock double-waterproofing system. The fluted bezel surrounds a scratch-resistant
sapphire crystal with a Cyclops lens — a hallmark of the Rolex Day-Date — magnifying the date in the window at 3 o’clock. The dials have a sunray finish and the hands and
appliqué indices are made of the same gold as the case.
Rolex Day-Date-White gold/blue The $100K Club Review dialThese colorful Rolex Day-Dates are powered by Rolex’s manufacture Caliber 3155, an automatic movement and
certified COSC chronometer. The blue Parachrom hairspring (Parachrom is another Rolex-exclusive alloy) in the movement’s oscillator is built to resist the influence of
magnetic fields and withstand extreme temperature variations. According to Rolex, this type of hairspring is also 10 times more shock-resistant than the traditional type.
Among the movement’s other attributes are a large balance wheel with variable inertia, a Breguet overcoil, a stop-seconds function for precise time-setting, and a power
reserve of around 48 hours.
The colorful straps, which create a monochromatic look paired with their matching dials, are of alligator leather and have 18k gold folding clasps outfitted with Rolex’s
Crownclasp system, which allows easy adjustment of the strap length. Prices on the five Rolex Day-Dates range from $23,000 to $25,000.
