http://www.thewatchbox.com/watches/panerai The Panerai Luminor Regatta Chronograph PAM 168 doesn’t jump off the wrist; it explodes. Armed with a weapons-grade iridescent blue metallic dial and day-glow Super LumiNova luminescent dial paint, this 40mm brushed titanium chronograph declares its limited edition status (399, to be precise) with the impact of a tactical nuclear strike. And speaking of nukes, that’s really the perfect reference point to describe this dial. While blue metallic Panerai dials have a long history dating to the early 2000s, this is no 224/8/9 “Firenze” or even the vivid blue of the PAM 82 “Marina Militare”; the Panerai Luminor Regatta PAM 168 positively GLOWS with the otherworldly dazzle of Cherenkov radiation (Uncanny, no? https://en.wikipedia.org/wiki/Cherenkov_radiation). But unlike the 47mm “Luminor 1950” cases, the Luminor Regatta Chrono PAM 168 doesn’t wear like a reactor core on your wrist. Its wieldy 40mm titanium case combines compact dimensions with the blissfully low mass of exotic titanium alloy. The PAM 168 is unmistakably a Panerai Luminor, but the fit and feel are ideal for those who like the look but favor the Rolex School of sports watch ergonomics. This Luminor Regatta is big enough to make a statement but ideally sized for a wide range of wrists. The PAM 168 stands apart from other Panerai Luminor models on that basis alone, but there's more to this dynamic device than its legendary movement. A compelling back story is part of the appeal. Built as a tribute model to support Panerai parent firm Richemont’s “Laureus Sport for Good Foundation,” the model year 2003 Panerai Luminor Regatta was designed to generate proceeds for the foundation’s mission of empowering underprivileged youth through the power of team sports. Beyond the “face value” of its riotous blue dial, the Panerai Luminor PAM 168 boasts a litany compelling highlights. The unconventional use of a tachymeter scale, tri-compax chronograph, 40mm case, and full-Arabic numerals distinguish this Luminor as a breed apart from its time-only oversized stablemates at the "Officine." Add the striking contrast between the polished steel bezel and the blue-grey titanium case, and the PAM 168 achieves individuality almost unheard of within the “Clone Wars” of Panerai’s back catalog. The combination of a polished steel bezel and brushed titanium case produces dramatic contrast, and the union of a 40mm case with the famed lightweight "gray metal" produces a sports watch that wears with sublime comfort. But it gets better; the PAM 168 features Panerai’s visually awesome bi-metallic bracelet. Its combination of brushed titanium, polished steel, and subtle visual echo of the Luminor crown guard are the stuff of dreams. Now discontinued, this bracelet is like catnip for collectors. Explicitly sporting in character, the PAM 168 is a Panerai that would appear at home trackside in Monaco or courtside at Madison Square Garden. The high-impact visuals of the chronograph and its calibrations are complemented by the contrasting effect of the blue dial , lime green highlights, and silver subdials. Because few Panerai Luminor models share this aesthetic, the owner of a PAM 168 is assured of exclusivity.
