The strongest Explorer II 216570 copy for most buyers is the 42 mm build that runs a working clone of the caliber 3187, keeps the correct hand stack, and matches the genuine 21 mm lug width. That mix is what separates a real 1:1 attempt from a watch that only photographs well. The checks below are the ones that matter on this reference: movement architecture, case thickness, the fixed 24-hour bezel, dial printing and hand order, bracelet fit, and water resistance. Packaging, holograms and certificates do not change what is on your wrist.
Tier 1: Clone 3187 With a True GMT Function
This is the top pick when a seller can prove the movement, not just name it. The 24-hour hand sits under the hour hand, and the hour hand jumps in one-hour steps without moving the minutes.
Explorer 2 216570 Replica Rolex: A Comprehensive Guide
Pros
- Correct hand stack, so the order of hands matches the genuine watch when viewed from the dial side.
- Jumping hour hand, which is the function the Explorer II is built around and the easiest thing to test in ten seconds.
- Case profile stays close to the original because the movement was designed as a GMT from the start, not adapted.
Cons
- Highest cost of the three tiers and the thinnest supply.
- Parts are harder to source, so some local watchmakers will decline service work.
- Sellers use the phrase loosely. Ask for a setting video that shows the hour hand jumping alone, or a photo with the case back removed.
Choose this tier if the watch gets regular wear and you want the crown to behave the way the genuine piece does.

Tier 2: 2836 or 2893 Base With a GMT Module
The middle option uses a proven Swiss-pattern base with a module stacked on top to drive the 24-hour hand. It runs well and keeps time, but the extra layer adds height.
Pros
- Easy to repair, and any competent watchmaker can service the base movement.
- Lower price than a true clone, with parts available almost anywhere.
- Stable timekeeping once regulated, which matters more than a spec sheet for daily wear.
Cons
- Case thickness often runs above the original, and that reads clearly on a 42 mm watch.
- Hand stack is frequently wrong, with the 24-hour hand riding on top of the hour hand.
- GMT hand sometimes moves with the hour hand instead of independently, which fails the core function.
This is the sensible pick for a first Explorer II if you accept a slightly thicker case.
Tier 3: Entry 2813 or 3804 Builds
Budget copies use a low-cost automatic with a slaved 24-hour hand. They look acceptable at arm's length and cost the least.
Pros
- Lowest entry point if you only want the silhouette and the orange hand.
- Cheap enough to treat as a beater or a travel watch you would not worry about losing.
Cons
- No independent hour setting, so the GMT hand is decoration rather than a tool.
- Finishing on the bezel numerals and dial print is usually soft, and lume is weak.
- Gaskets are often dry, so swimming is a gamble without a pressure test.
Case and Bezel Checks
The genuine 216570 measures 42 mm across, uses a 21 mm lug width, and carries a fixed steel 24-hour bezel with engraved numerals filled in black. Run a ruler across the lugs: a 22 mm bracelet squeezed into 21 mm lugs will show gaps at the end links. On the bezel, look at numeral thickness and the fill. Sharp edges and uneven black paint are the fastest tells. The crystal is flat sapphire with no cyclops over the date, so any magnifier bubble is an immediate fail.
Dial, Date and Hand Order
On the black dial the words EXPLORER II are printed in orange. On the white dial they are black, and the 24-hour hand stays orange on both. Markers are large applied units with blue lume. Check that the date window is square and centered at 3, that the date disc color suits the dial variant, and that the rehaut engraving sits straight around the whole chapter ring. A tilted or blurred rehaut shows up in daylight.
Bracelet and Case Back
The Oyster bracelet should taper, flex without rattling, and close with a clasp that has a fold-over safety and a short extension link. Solid end links should sit flush against the case with no visible daylight. The case back is solid steel. A display back with a glass window is wrong for this reference, no matter how nice the movement looks.
Water Resistance and Service
The original is rated to 100 m. Treat any copy as unsealed until proven otherwise. Have a watchmaker pressure test it, replace the gaskets if needed, and check the crown threads. Plan on a service every few years, and keep it away from hot water and soap, which break down seals faster than swimming does.
Which Build Fits Your Use
For a daily wearer where the jumping hour hand gets used on flights, buy Tier 1 and confirm the movement with a video before paying. For a weekend piece where thickness is a fair trade for easy repairs, Tier 2 is the practical answer. For a low-cost travel watch, Tier 3 works if you never take it in the water. In every tier, judge the seller by whether they will show the movement, the lug width and a lume shot before the sale.
