Hanboro 018 Steel King — Micro-Rotor Automatic Watch

Hanboro 018 Steel King — Micro-Rotor Automatic Watch

An octagonal, slim-cased automatic that leans dressy without going soft. The faceted “porthole” bezel and integrated bracelet run in one unbroken line, diamond-cut edges catching the light against brushed steel. Behind the sapphire crystal sits a matte textured dial with applied faceted markers, 12 and 6 o’clock numerals, luminous hands and markers, and a date window at 3 o’clock.

The reason it wears so thin — just 9 mm — is the movement. Instead of a full-size winding rotor, this automatic uses a compact micro-rotor (Hanboro calls it the “pearl rotor”): a small off-centre weight that winds the mainspring as you move, while taking up far less height. It runs at 28,800 vibrations per hour with a stated 60-hour power reserve, and you can watch it turn through the exhibition caseback — each one individually numbered. If you already like the brand, the Hanboro Chime 9015 automatic takes the same self-winding route with a chiming twist.

At 40 mm across with a double-push butterfly clasp, it’s an easy everyday size — and it sits right alongside the octagonal-design automatics buyers cross-shop in this style. Choose grey, black or blue on stainless steel, or a warm rose-gold-tone finish with a champagne dial. Every watch ships with a matching fitted rubber gift strap, so you can switch from bracelet to sporty in seconds.

Specifications

Wearing & care

Rated 10 ATM (100 m): fine for rain, splashes, handwashing and brief swimming — not for diving, hot showers or the sauna, and never operate the crown in water. As an automatic it winds from wrist movement; if left off for a day or two it will stop, so give the crown a few turns and reset the time before wearing. Wipe with a soft cloth and keep it away from strong magnets and hard knocks.

FAQ

Is the Hanboro 018 a tourbillon watch?
No. The 018 is an automatic (self-winding) watch with a micro-rotor — sometimes called a “pearl rotor.” A micro-rotor is a compact, off-centre winding weight; it is not a tourbillon, which is a rotating escapement cage. The 018 does not have a tourbillon.

Is the Hanboro 018 automatic or quartz?
It’s a mechanical automatic that winds from the motion of your wrist — no battery. It beats at 28,800 vibrations per hour with a stated power reserve of about 60 hours, and you can see it run through the exhibition caseback.

Can I swim with the Hanboro 018?
It’s rated 10 ATM (100 m): fine for rain, splashes, handwashing and brief swimming, but not for diving, hot showers or the sauna. Never operate the crown while the watch is in water.

What size is the Hanboro 018?
The stainless steel case is 40 mm in diameter and just 9 mm thick, with a 20 mm lug width. It weighs about 130 g on the bracelet.

Does the Hanboro 018 have a sapphire crystal?
Yes — it uses a sapphire crystal, which is highly scratch resistant.
