TRN-50-2A — Casiotron for 50th Anniversary

Join us in celebrating the golden jubilee of Casio watches with the exclusive and brand-new Casiotron limited edition. This remarkable timepiece is a tribute to the very first Casio wristwatch ever created. When it made its debut in 1974, the Casiotron revolutionized the watch industry as the world’s inaugural digital watch equipped with an automatic calendar that intelligently adjusted to accommodate varying month lengths. The all-new TRN-50 seamlessly blends the essence of the original masterpiece with cutting-edge modern technology. Painstakingly crafted to faithfully replicate the original design in both appearance and size, the external diameter remains virtually unchanged at 39.1mm, while the profile boasts a slimmer 0.3mm. Throughout this exclusive edition, you’ll discover subtle nods to the inaugural model, from the textured case and band to the striking dark blue dial adorned with the iconic Casiotron logo. Countless other meticulous details pay homage to the distinctive first design.
The case back proudly showcases the same emblem as the original, albeit with a slight update to commemorate the momentous 50th anniversary of Casio watches. Each limited-edition timepiece bears a unique engraved serial number (0001/4000 – 4000/4000), serving as a testament to the rarity of these extraordinary watches.
