If you’ve been following along, you already know we’ve been shining a spotlight on the unique charm of the Calendar Auto Orient Diver series. While many Japanese brands played it safe with their designs, Orient boldly broke the mold, creating one of the most iconic —and still underrated— divers out there.
This series is known for its variety of dial configurations and distinctive cases, but it’s the case that truly steals the show: Thick and commanding from above, yet dramatically sloping from the side, striking the perfect balance between boldness and elegance. Today, we’re excited to offer a pristine, unworn Calendar Auto Orient T19735A.
Let's start with the dial: Clean matte black, classic, and full of subtle flair. Those applied luminous indexes don’t just sit pretty, they sparkle, especially the jewel-like 6, 9, and 12 markers that catch light with their pointed facets. The arrow hour hand and dagger minute hand bring a touch of drama, while the white-on-white date window keeps things cohesive. This diver is all about sharp angles and crisp lines, and the flat crystal just leans into that geometry.
Flip it over and a stunning engraving reveals itself: “Diver,” “Perfect Water Proof,” “Stainless Steel,” and the T19735 reference number, all still guarded by the faded remnants of the original blue sticker. Inside, a reliable 21-jewel automatic movement Cal.670 quietly ticks away, with the added bonus of hand-winding capability.
And the final cherry on top? This one’s still riding on its original stainless steel bracelet, a rarity that just completes the whole look. Tropic straps are surely fine, but this bracelet? Chef’s kiss.
The T19735A is one of those watches that barely leaves a digital footprint, and that tracks, given how rare they are. This particular example is even more special: Originally unsold, it was discovered complete with the watch store’s original price tag still attached. It’s a quiet masterpiece, a reflection of the care and creativity that defined Orient’s golden era.
The watch currently works flawlessly and it will be serviced once purchased. Please expect 1-2 months before delivery.
