The straight answer: the Explorer II 226570 is a 42 mm Oystersteel GMT watch with a fixed 24-hour bezel and the calibre 3285, and watches sold as "fake Rolex Explorer 226570" do not match it in function, materials, or legal standing. This guide will not walk you through where to buy counterfeits. It explains what the reference actually is, why replica listings for it fall short, and which legitimate GMT watches deliver the closest experience. Every option below is judged on four criteria: whether the 24-hour hand works like the genuine one, case size and wrist comfort, movement serviceability by an independent watchmaker, and what happens if you need warranty support or decide to sell.

What the Genuine Explorer II 226570 Actually Is

Rolex introduced the 226570 in 2021, replacing the 216570. The case is 42 mm in Oystersteel with a fixed steel 24-hour bezel, water resistance rated to 100 metres, and a choice of black or white dial. The movement is the calibre 3285, the same family used in the GMT-Master II, with a 70-hour power reserve and an independent 12-hour hand that jumps in one-hour steps. That jumping hour hand is the core of the design. You land in a new time zone, pull the crown, and set the local time while the 24-hour hand keeps home time. The bracelet is Oyster-style with an Oysterlock clasp and the Easylink extension.

Why Replica 226570 Listings Fall Short

Replica sellers advertise the 226570 constantly, and the gap between the listing and the object is wide.

• Movement architecture: Many replicas use a 24-hour hand that is geared to the main hour hand instead of an independently jumping 12-hour hand. On those watches, changing the local time drags the home-time reading with it, which defeats the point of the complication.
• Steel and finishing: Oystersteel is a 904L-family alloy. Most replica cases and bracelets are 316L, which takes a slightly different polish and shows wear differently.
• Bracelet fit: Solid end link fit, clasp action, and screw-link tolerance are where fakes are easiest to spot on a wrist.
• Service: No watchmaker can get genuine Rolex parts for a counterfeit case. Independent shops often decline the work, and Rolex service centres will not touch it.
• Legal exposure: Trademark counterfeiting is a federal crime in the United States under 18 U.S.C. 2320, and shipments of counterfeit goods are subject to seizure. There is no lawful resale path, which means no recovery of what you paid.
• Resale value: Zero. A replica is worth nothing on the secondary market, while a genuine reference holds a large share of its value.

Legitimate Alternative 1: Seiko 5 Sports GMT

The Seiko 5 Sports GMT family, including the SSK001 and its siblings, is the most practical entry point for anyone who wants a steel sports watch with a 24-hour hand. The 4R34 movement gives you an independently settable 24-hour hand, automatic winding, and a date.

• Plus: In-house movement with a real GMT hand, wide dealer network, easy service, and a price that leaves room for a second watch.
• Plus: Hardened case and bracelet finish holds up to daily wear.
• Minus: Around 42.5 mm and fairly thick, so it wears larger than the 226570 for many wrists.
• Minus: Accuracy is quoted in broad ranges rather than chronometer standards.

Best for: A first GMT, travel beater, or anyone who wants the function without the commitment.

Legitimate Alternative 2: Longines Spirit Zulu Time

The Zulu Time is a true travel GMT with an independently jumping local hour hand, a 42 mm steel case, and a Longines L844.5 automatic movement with a 72-hour power reserve. Dial finishing, applied numerals, and case bevels sit well above the entry tier.

• Plus: Genuine traveller GMT behaviour, long power reserve, and strong case finishing.
• Plus: Authorised dealer support, so warranty and service are straightforward.
• Minus: Costs several times a Seiko GMT and holds value less well than a Rolex.
• Minus: The 42 mm case and long lugs need a larger wrist.

Best for: Buyers who want the full GMT experience with formal service backing.

Legitimate Alternative 3: Longines HydroConquest GMT

If you want the 100-metre-plus water resistance and the sportier look of an Explorer II, the HydroConquest GMT covers it with a 41 mm case, screw-down crown, and the same L844.5 family of movement with an independent local hour hand.

• Plus: Diver-grade sealing and a bracelet with a proper dive extension.
• Plus: Smaller case diameter suits more wrists than the Zulu Time.
• Minus: The bezel is a dive scale, so you lose the fixed 24-hour track that defines the Explorer II look.
• Minus: Heavier and thicker on the wrist than the standard three-hand version.

Best for: Swimming, beach travel, and anyone who prefers a rotating bezel to a fixed one.

How to Tell a Real 226570 From a Fake

If your interest is buying a genuine watch rather than a replica, these are the checks that matter.

1. Dial and printing: The coronet is applied and sharply finished, and the text is crisp with consistent spacing. Fakes show thick or doubled printing.
2. Cyclops and date: The magnifier sits centred over the date window and the date disc font is clean and properly aligned.
3. Jumping hour hand: Set the local hour and confirm the 24-hour hand stays put. A fake with a linked GMT hand will fail this test.
4. Caseback and rehaut: The caseback is smooth, and the rehaut carries engraved repeating ROLEX text that lines up with the dial.
5. Bracelet clasp: Look for the engraved STEELINOX marking, a smooth Oysterlock action, and solid end links with no play.
6. Paperwork: A warranty card with a matching serial, reference, and date, plus a check of the serial against the case between the lugs.
7. Authentication: Have a reputable dealer or watchmaker open the case and confirm the movement. This is the only step that settles it.

Bottom Line

Do not spend money on a fake 226570. You lose the jumping-hour GMT function, the steel quality, any service path, and legal standing, and you recover nothing if you sell. If you want the look and the 24-hour hand today, buy a Seiko 5 Sports GMT. If you want a serious travel GMT with dealer support, the Longines Spirit Zulu Time or HydroConquest GMT is the right move. If only the genuine article will do, buy a used Explorer II through a trusted dealer with a documented service history, and budget for a service interval the same way you would for any mechanical watch.
