Most retro watch revivals bring back a case shape, a dial color, or a logo. The Seiko HFL001 Rotocall brings back a stranger idea: using the bezel to change modes on a digital watch.

That is the hook here. The HFL001 is a Seiko 145th Anniversary Limited Edition based on the 1982 Rotocall, a digital quartz watch built around a rotary switch. Seiko says the original design gained international recognition partly because of its popularity among astronauts, and the 2026 version turns that old interface into a limited-edition release with Edo purple as the visual anchor.
The Bezel Is the Whole Point
The HFL001 isn’t trying to look like every other heritage reissue in Seiko’s 2026 anniversary run. It is a digital quartz watch with a rotating bezel that controls modes, which immediately gives it a different reason to exist than another mechanical diver or dress watch with a special dial.
Seiko lists a rotary switch as one of the A824 caliber’s functions, alongside a counter, chronograph, alarm, timer, dual-time display, full auto calendar, battery-life warning, and LED illumination. The chronograph runs up to 100 hours in 1/100-second increments, while the timer runs up to 100 minutes in 1-minute increments.
That combination gives the HFL001 a very specific personality. It is digital, practical, and a little odd, but the oddness is the feature rather than a side effect.
Seiko Went Purple for Its 145th Anniversary
The Seiko HFL001 Rotocall sits inside Seiko’s third series of commemorative limited-edition watches for the brand’s 145th anniversary. Seiko says the central design idea is Edo purple, a color tied to traditions carried from ancient Edo into modern Tokyo.
On this model, that means a black stainless steel case and bracelet with hard coating, a purple aluminum bezel, and gold-tone accents. It is a louder color story than the spec sheet suggests, but the black case and bracelet keep it from turning cartoonish.
The limited-edition count matters here. Seiko says the HFL001 will be made in 4,000 pieces, with “LIMITED EDITION” on the case back. The official US price is USD 595.00.
The Size Keeps It Wearable
The case measures 37.0mm across, 10.6mm thick, and 43.5mm lug to lug. Those numbers put it in a wearable zone for a digital watch with a bracelet, especially compared with bulkier modern sports watches that often ask your wrist to carry the whole spec sheet.
The case uses stainless steel with hard coating and a Hardlex crystal. Seiko also lists 10 bar water resistance, a screw case back, a three-fold clasp with push-button release, and a 20mm distance between the lugs.
That price now gives the HFL001 a clearer position: collectible enough for Seiko fans, but not priced like one of the brand’s higher-end mechanical anniversary pieces.
Why This One Feels Different From a Normal Reissue
Most heritage watches ask you to care because they look like something old. The HFL001 asks you to care because it works like something old.
That distinction gives the watch a better story. The rotary bezel isn’t decoration. It changes how you interact with the watch, which makes the Rotocall connection more than a name-drop.
Seiko recently brought the Rotocall line back with gold and silver versions, and the HFL001 now gives that revival an anniversary version with an Edo purple bezel and a 4,000-piece cap. For readers who already know Seiko’s dive watches, field watches, and dress-watch reissues, a digital model with a physical mode selector gives the anniversary collection a different kind of texture.
It also lands at a useful moment. Casio-style digital nostalgia, calculator-watch weirdness, and small retro electronics all have a real audience again. The HFL001 doesn’t need to pretend to be a smartwatch. It is more interesting as a purpose-built digital watch with one tactile trick.
Who Should Care, and Who Should Skip It
This is for Seiko fans who want something stranger than another anniversary diver. It also makes sense for collectors who like digital watches, space-age interface ideas, and limited editions that do more than change a dial color.
Skip it if you want sapphire, mechanical movement, or a conventional daily watch that disappears under a cuff. The HFL001 uses Hardlex, runs on quartz, and announces itself through the purple bezel before you even touch the rotary control.

The best part is that Seiko didn’t overcomplicate the concept. The HFL001 is a compact digital watch with a real interface story, a 4,000-piece cap, and a color palette tied to Tokyo heritage. That is enough.
