A fake Rolex 5513 Big Triangle is a replica of a vintage no-date Submariner dial variant, so the buying decision should turn on visual accuracy and serviceability, not on a Swiss label. Buy the example with the most accurate case and dial geometry, a movement a watchmaker can service, and a seller who states clearly that it is a replica and offers a return window. Do not pay extra for vague claims or treat any replica as an investment. Check the legal position where you live, and never accept a replica sold as genuine.

What to look for first

The 5513 Big Triangle should read as a no-date Submariner. The name comes from the oversized triangle marker at 12 o'clock. A date window, a Cyclops, or a dial that says Submariner with extra text where the original did not can be immediate mismatches. Start with the case profile: crown guards, lug shape, and the transition from the bezel to the mid-case matter more than a glossy marketing page. Check that the dial markers, hands, and bezel insert share the same design language. The crystal should suit the vintage look, which usually means a domed acrylic crystal rather than a flat sapphire. Confirm the caseback is plain and the crown sits correctly in the guards.

Parameter bands to expect

  • Case size: about 40 mm across, with roughly 20 mm lugs. A noticeably larger or smaller case changes the look.
  • Thickness: often around 14 mm to 15 mm depending on the movement and caseback. A date movement can add height and parts you do not need.
  • Dial: matte black finish, large triangle at 12, round and rectangular markers, no date opening. Lume color should be consistent across dial and hands.
  • Bezel: 60-minute dive insert with a pearl at 12. Font, marker shape, and pearl position are common accuracy points.
  • Crystal: domed acrylic is the vintage-correct choice for a 5513-style build. Sapphire can be fine for daily wear but is not period-correct.
  • Movement: a no-date automatic is the cleanest choice. Ask for the movement type and whether parts are available. A serviceable Asian or ETA-style unit is more useful than an unknown Swiss claim.
  • Water resistance: treat any claim as unproven until a watchmaker pressure tests the actual watch. Vintage-style seals and acrylic crystals are not a diving guarantee.

Seller and transaction checks

Ask for current photos with a timestamp, not catalog images. Request close-ups of the dial, crown guards, lug holes, bezel insert, caseback, and movement. A seller who will not show the movement or the caseback is a risk. Get the return terms in writing before payment. Confirm that the seller discloses the watch as a replica and does not use genuine Rolex paperwork or packaging to imply authenticity. Use a payment method with buyer protection. Keep the listing and messages. If the seller claims Swiss made without explaining the movement, treat that as marketing noise rather than a specification.

Pitfalls that cost money

  • Paying a premium for super clone language with no movement photos or service plan.
  • Accepting a date model as a 5513. A no-date Submariner should not have a date window or Cyclops.
  • Missing the Big Triangle detail. A standard marker at 12 changes the entire dial character.
  • Ignoring case geometry. Wrong crown guards or lug shape are harder to fix than a bezel insert.
  • Believing water resistance claims without a pressure test.
  • Treating a replica as a collectible or an investment. It is not a genuine vintage Rolex.
  • Overlooking legal risk. Counterfeit trademark goods can be seized, and sellers can face civil or criminal enforcement.

FAQ

Is a fake Rolex 5513 Big Triangle legal to buy in the US?

Counterfeit goods carry legal risk in the US. Customs can seize counterfeit merchandise, and trademark owners can pursue sellers. Buying for personal use does not make the trademark issue disappear. Check the current rules and avoid any deal that depends on hiding what the watch is.

What is the biggest tell on a replica 5513 Big Triangle?

Case and dial geometry. Look at the crown guards, lug shape, marker size, and the 12 o'clock triangle. A wrong crystal or bezel insert is easier to spot, but a wrong case is harder to correct.

Should I pay more for a Swiss movement?

Only if the seller documents the movement and a watchmaker can service it. A known, serviceable movement with available parts is worth more than an unverified Swiss label.

Can I swim with a replica 5513?

Do not assume so. Have the case opened, seals checked, and the watch pressure tested by a watchmaker. Even then, vintage-style construction has limits.

What should I ask before payment?

Ask for timestamped photos, movement photos, the exact case size, the crystal type, the return window, and written disclosure that the watch is a replica. If any answer is vague, walk away.
