A replica Rolex Submariner 16613 is a copy of the two-tone steel and gold Submariner Date, the reference best known in its blue dial form. A faithful replica should match the original 40mm case, the yellow gold bezel and crown, the gold center links on the Oyster bracelet, and the date window under a cyclops lens. Beyond those basics, versions differ most in the movement inside and in how the gold is applied.

What the Original 16613 Stands For

Reference 16613 belongs to the Submariner Date family. It pairs a stainless steel case and case back with an 18k yellow gold bezel, winding crown, and bracelet center links. Rolex offered several dials over the years: the blue sunburst dial that earned the nickname Bluesy, a black dial, and champagne Serti dials with gem-set hour markers. The reference was produced from the late 1980s into the late 2000s, and small details changed along the way.

Since the original is out of production and secondary market prices are high, the 16613 became a popular subject for replica makers. Buyers are usually drawn to the look rather than the collectible value, and that is the right frame when comparing versions.

Materials and Finish

Two-tone watches live or die by how the gold reads next to the steel, so start there.

  • Case steel: Most replicas use 316L stainless steel. Higher tiers use 904L, which polishes closer to the original luster.
  • Gold application: Plating is the thinnest and cheapest route. PVD adds a layer that resists wear better. Wrapped or filled gold uses a thicker bonded layer and holds color longer.
  • Color match: Real 18k yellow gold has a warm, slightly muted tone. A replica that looks brassy or orange in daylight will not match.
  • Bezel insert: The 16613 uses an aluminum insert, not ceramic. A glossy ceramic insert on this reference is the wrong detail.
  • Crystal: Sapphire with a cyclops magnifier over the date. Check that the magnifier sits centered and does not smear the date.

Movement Choices

The movement is the biggest price divider. There are three common routes:

  • Asian automatic: Entry level, decent timekeeping, cheapest to replace.
  • ETA 2824 or 2836 based: A proven Swiss-designed architecture that runs at 28,800 vibrations per hour, giving an eight-beat-per-second sweep. Service parts are easy to source.
  • Clone 3135: Copies the layout of the movement Rolex used, including crown winding direction and quickset date. The most faithful option and the most expensive to repair.

A healthy automatic should hack, meaning the seconds hand stops when the crown is pulled out, and should sweep steadily instead of stuttering. Ask for a timegrapher reading if the seller can provide one.

Dial and Bracelet Checks

  • Print quality: text sharp and evenly spaced, with no fuzzy edges.
  • Lume plots: round, evenly filled, and aligned with the markers.
  • Rehaut: the inner ring between dial and crystal should be polished and engraved consistently.
  • Bracelet: solid links, no hollow rattle, and a clasp that closes with a firm click.
  • End link fit: they should sit flush against the case with no visible gaps.

Sizing, Weight, and Daily Wear

The 16613 measures 40mm across with a 20mm lug width. On the wrist it wears a little smaller than that number suggests because of the slim lugs and tapered bracelet. Weight is a common giveaway. A two-tone watch should feel substantial, in line with a steel sports watch plus the gold content. If a replica feels light in the hand, the gold layer is likely thin.

Water Resistance and Care

Do not assume a replica is safe for swimming. Gasket quality and case sealing vary, and a depth rating printed on a case back means nothing without a pressure test. Wear it for daily use, keep it away from chlorine and salt water, and wipe the case with a soft cloth after contact with sweat or sunscreen. If the gold starts to fade at the crown or clasp, a jeweler can often re-plate those small areas.

Quick Buying Checklist

  1. Confirm the reference details: aluminum bezel insert, 40mm case, cyclops over the date.
  2. Ask which movement is inside and whether it hacks.
  3. Request photos in natural light so the gold tone is honest.
  4. Check bracelet end link fit and clasp action.
  5. Ask about the warranty and whether the seller regulates the movement before shipping.

FAQ

Is the 16613 the same as the Bluesy?

Bluesy is the nickname for the two-tone Submariner with a blue dial and blue bezel insert. The 16613 is one of the references that carries that nickname.

What size is a replica Rolex Submariner 16613?

A correct example should measure 40mm across the case with a 20mm lug width, matching the original.

Which movement should I pick?

For daily wear, a Swiss-designed automatic such as the 2836 keeps good time and is simple to service. If matching the original layout matters more, a clone 3135 is the closer choice.
