Description

The ocean-ready classic, kept simple in black.

If you only wear one watch, this is the shape and this is the colour. A black dial reads instantly in any light, the dive bezel gives the case its purposeful shoulders, and the Milanese mesh softens the whole thing so it never feels like gear.

Specifications

Movement: Seiko NH35 automatic
Case: ~41.5mm stainless steel
Crystal: Sapphire
Dial & bezel: Black dial, rotating dive bezel, stainless steel case and bracelet
Strap: Milanese mesh bracelet
Water resistance: Everyday wear (splash-resistant, not dive-rated)

The engine is a genuine Seiko NH35 automatic, chosen because it refuses to be precious: hackable, hand-windable, 21,600 beats per hour, 41 hours of reserve, and famously cheap to keep healthy for the long haul.

Before it ships, I photograph your watch and send it to you. Not a stock photo of the model. The actual one going in your box.

Add it to your cart and I will get it started.

What's included

Shipping

Warranty and returns

You're paying for the watch, not the name.

Two things make a five figure watch five figures: what it is, and what it is called. The steel, the crystal, the movement, the dial work. That is the watch. The name, the boutique, the waiting list, a century of advertising. That is the rest. Rosevari builds the first part and leaves the second part out.

From your order to your wrist

Built to order

Your watch is assembled to the specification you choose, by our workshop overseas.

Photos before it ships

You get photos of your finished watch. Yours, not a stock image.

Shipped tracked and insured

Free worldwide shipping, with tracking the moment it leaves.

Water resistant

Splash-resistant as standard, built for daily wear, rain and hand washing. Swim-Ready and Dive-Ready upgrades available.

Sapphire crystal

Fitted with sapphire crystal, ultra-clear, scratch-resistant. Your watch stays sharp, no matter what.

Stainless steel

316L marine-grade stainless steel, the same steel used in dive watches. Built to shrug off daily wear.

Movement

Genuine Seiko and Miyota movements, the same calibres trusted across the watch industry. Each watch lists its exact movement in the specs.

Superior materials

Genuine calibers and high-grade cases, crystals, and bracelets for real-world durability and performance.

Guaranteed quality

Every watch passes strict multi-point QC before it ships, so you receive a timepiece you can trust.

Questions, answered

Is it guaranteed? +

Yes. Every Rosevari carries a one year warranty against manufacturing faults in the movement, crystal, case and dial. Faulty, damaged or not as described within 30 days of delivery: we repair, replace or refund, and postage both ways is ours, anywhere in the world. After 30 days the warranty still covers you for the full year; you cover the postage to us. Australian customers also hold consumer guarantees under the Australian Consumer Law, which can last longer than any warranty.

What do I say when someone asks if it's real? +

Tell them what it is. A homage, with a genuine Seiko or Miyota movement inside, and you paid for the watch, not the name.

Is it legal to own and wear? +

Yes. Homage watches are legal to buy, own and wear.

Can I swim with it? +

Not as standard. Every watch is splash-resistant: rain, hand washing and everyday wear are fine, swimming, showering and diving are not. If you want it swim-safe, choose Swim-Ready (5 ATM) on this page, or Dive-Ready (10 ATM) on Submariners. It is sealed during the build, so it has to be chosen when you order. With any water rating, screw the crown down tight before the watch goes near water: an unlocked crown is the most common way a watch floods, and that is not covered by the warranty.

How long does it take, and what does shipping cost? +

Shipping is free worldwide, with no minimum, and every order is sent tracked and fully insured. Your watch is built to order. Typically 2 to 3 weeks to build, please allow up to 4. After dispatch, most orders arrive in 6 to 12 business days worldwide, or 2 to 3 business days within Australia. You get tracking the moment it ships.

What if I change my mind, or something is wrong? +

Every watch is built to the specification you choose, so we do not take change-of-mind returns. If you change your mind before the build starts, email us within 24 hours of ordering and we cancel and refund in full, no questions asked. If it is faulty, damaged, the wrong model or not as described, you have 30 days from delivery and we cover postage both ways.

Why is this so much less than the watch it resembles? +

Because you are paying for the watch, not the name. Inside is a genuine Seiko or Miyota movement, under a sapphire crystal, in a 316L marine-grade steel case. What you are not paying for is a century of advertising and a jeweller's showroom.

Will it fit my wrist? +

Most of our cases run 36mm to 41mm, which suits the majority of wrists. Our sizing guide matches your wrist measurement to a case size, and if you are between sizes email us before you order and we will tell you straight.

What comes in the box? +

Your watch, a travel case and a sizing tool, with every order. Every watch is also covered by our online Owner's Manual: how to wind and set your movement, size the bracelet, and what the water rating really means.
