ChronoTheory & Co is an independent watchmaking project initiated by CHRONOTHEORY, a high-end luxury watch boutique and retailer located in the Ginza district of Tokyo, Japan. The initiative was led by the retailer’s representative and designer Watanabe, a former graphic designer with experience in business design and advertising, along with in-house watchmaker Yutaro Iizuka, an alumnus of the Hiko Mizuno College of Jewelry and winner of the 2018 Walter Lange Watchmaking Excellence Award. The “ampersand Co” in the brand’s name signifies a collaborative push onto the global stage alongside specialized Japanese manufacturing partners and craftsmen from diverse technical fields.
Collectors and watch enthusiasts appreciate ChronoTheory & Co for its blend of mid-20th-century horological aesthetics with high-precision modern Japanese manufacturing techniques. Instead of operating as a traditional standalone manufacture, the project collaborates with top-tier domestic suppliers. For instance, the watch cases are crafted and Zaratsu-polished by Kyowa Seiko Co., Ltd.—the manufacturer behind the MINASE brand—while the intricate dials are produced by Shoko-sha, a historical dial maker operating since 1929. Rather than standard presentation boxes, each timepiece is delivered with the “WATCHCUBE,” a custom-designed leather carrying case built specifically for daily travel and protection.
The flagship model introduced by the brand is the AV-98, which stands for “Advanced Vintage 6498”. Powered by a hand-finished, manually wound ETA 6498-1 movement, the AV-98 features a 42mm stainless steel case inspired by 1930s to 1950s dress watches, offering 6 bar water resistance. Its dial showcases applied Breguet numerals, multi-layered lacquering, and hand-chamfered hands. The AV-98 was launched in three colorways: Piano Forte Black with yellow gold indices, Strato Navy with silver indices, and Timpani Rose featuring a hairline bronze finish with silver indices.
