http://www.thewatchbox.com The early 1970s were the heyday of the "motorsports" chronograph, and Oris launched the original Chronoris Star to grab a piece of the action. With the reborn 40mm Oris Chronoris chronograph, the watchmaker from Hölstein returns to the track with style. In 1970, the watchmaking world and the race community were in step. The Rolex Daytona, Heuer Monaco, Autavia, and Carerra, Omega Speedmaster Mark II "Racing Dial," and yes, the Chronoris Star, graced the wrists of race car drivers at events as varied as, well, Daytona and Monaco. Oris' 21st century Chronoris captures the look and character of the original. Start with the case; it's a classic early 1970s "cushion" profile that splits the difference between a classic round watch and a hardboiled egg. Enthusiasts of 70s retro style wouldn't have it any other way; consider the recent frenzied market reaction to the reissued Omega Bullhead and Speedmaster Mark II as Exhibits A and B, respectively. More than a period piece, the 5-ATM water resistant Oris case packs a useful feature: the Oris Quick Lock Crown. Only a half-turn is required to lock and unlock the crown for a hermetic seal or easy access to setting functions. While the 1970s was the era of Earth Tones in the home, it was the era of day-glow colors on the wrist. The Chronoris chronograph offers an orange-black-white palette that is both period-correct and delightfully legible. An outer tachymeter scale keeps the "track day" theme and functionality intact. Oris improves upon the seconds-only 1970 chronograph original by adding a 30-minute register at 12 o'clock; the date window provides a visual counterweight at 6. Within the stainless steel case, an automatic Oris caliber 672 based on the Valjoux/ETA 7750 keeps the beat with legendary durability. Oris knows that not all collectors wish to take the 70s flashback to the extreme, so the black and orange perforated calf leather strap is accompanied by a steel link bracelet that lowers the visual volume for times when business suits replace Nomex suits - like when you're negotiating with your racing team sponsors. Even better, Oris includes a jeweler's tool, spare spring bars, and a deluxe leather carrying case for easy trackside "pit stops" involving DIY strap changes.
