Challenge Regatta 2007. Bubble One of Corum's most iconic and recognizable series, produced from the beginning of the 2000s to the end of the decade. In 2015 this line was reintroduced with different materials. Created by the owner of the brand at the time, legendary Severin Wunderman, with a bold design and an unusual huge sapphire glass face - the line was available in three sizes - mini (26 mm), midsize (35mm) and XXL version of 45mm. The XXL has had over ten different limited editions, rare and highly sought after. Among them are Lucifer, Baron Samedi, Bats, Joker, Royal Flush, etc. Buckingham Released in the 1960s, the model is still produced. Part of the "dress" line of the brand, the model currently features a square 37mm x 37mm case, equipped with either an alligator leather strap or stainless steel Corum-branded mesh, integrated into the case. The model is available with either a quartz movement or a manually-wound ETA (Peseux) 7001 movement. Some older models are available with automatic movements. Dials use index markers or English/French wording. Romulus Created in 1966, the Corum Romulus was the first Corum watch to display the hour numerals on the bezel. It sports a sapphire case back engraved with a laurel crown in honor of Romulus, the founder of ancient Rome. It is available in stainless steel, white or yellow gold and a dual time version in either yellow or white gold. The modern models are available in 40 mm or, more recently, 42 mm cases and leather straps or steel bracelets. Golden Bridge The Corum Golden Bridge collection is unique in the watchmaking world. Its four sapphire sides offer an unrestricted view of the intricately detailed linear movement, which appears to be floating in mid-air, held only by the gold bridge that names this watch. The Corum Golden Bridge is offered in 18k gold or platinum, and is also available with delicate diamond work. Tourbillon and Classical The Corum Tourbillon and Classical collection comprise the Corum Classical Billionaire Tourbillon, a diamond and sapphire-covered masterpiece of watchmaking, the Corum Golden Tourbillon Panoramique with its tourbillon movement floating between sapphire bridges, and the skeleton-dialed Corum Classical Skylight Skeleton.
