The short answer

No factory builds a faithful replica of the Rolex reference 6062. The real watch is a roughly 36mm Oyster case with a triple calendar (day, date, month) and a moonphase, and that combination has never been reproduced at replica prices. What gets sold under this name is usually a three-hand Oyster-style case with a printed dial, a moonphase window that either turns once every 24 hours or never moves at all, and a crown that only winds and sets the time. Treated as a costume piece, it is fine. Treated as a stand-in for the real thing, it falls apart the moment someone who knows watches looks at it.

What the genuine 6062 is

Rolex produced the 6062 in the early 1950s, and it remains one of only two serially produced Rolex references with a moonphase, the other being the 8171. Total output is generally estimated at around 300 to 350 pieces across stainless steel, yellow gold, and pink gold, with steel examples the rarest by a wide margin. That scarcity is why auction houses treat them as headline lots. The dial most people picture is the 'Stelline,' with star shaped hour markers, and the best known example is the yellow gold 6062 called the Bao Dai, which sold in Geneva in May 2017 for CHF 5,066,000.

Where 'bailer' comes from

The word is almost always a garbled version of something else, and the name that gets mangled most often is Beyer, the Zurich watch house that co-signed dials on rare Rolex models. Searches for 'bailer' and 'beyer' land in the same place, and both describe one thing: a dial printed with a retailer name alongside Rolex. On a genuine 6062 that printing is part of the provenance puzzle and adds real money at auction. On a replica it is a fantasy detail, since the factories copy the look of a co-signed dial with no connection to the retailer that supposedly sold it.

What replica versions get wrong

• Case proportions. The 6062 sits near 36mm with slim lugs and a thin bezel. Most replica cases run larger and thicker, which changes how the dial reads on the wrist.
• The moonphase. A real moonphase runs on a 29.5 day cycle. Replica versions typically show a disc tied to the hour hand, or a static aperture under a printed moon.
• Calendar corrections. A genuine 6062 sets day, date, and month through the crown. Replica movements rarely offer more than a date, and often not even that.
• Dial work. Star markers, applied versus printed, and the finish on the moonphase disc are the first details to give a replica away in hand.
• Finishing. Lugs, crown, and caseback engraving are where cheap cases show machining marks and soft edges.

How to size one up if you are offered it

Start with the dial, not the movement. Check whether the day and month windows are cut into the dial or printed on top of it, whether the star markers sit above the surface or lie flat, and whether the moonphase disc advances when you move the hands forward. Then check the case: measure it, feel the lug edges, and look at the crown for a signature that matches the rest of the watch. A working moonphase in a small case does not exist at replica prices, so if a seller claims one, ask for a movement photo and a short video of the moonphase moving.

Risk worth pricing in

Replica watches are counterfeit goods. They can be seized by US Customs, they carry no warranty or parts support, and they have no resale market, so the money is gone the day the package arrives. Rolex will not service one, and many independent watchmakers will not touch a movement with no parts supply. That is the part of the math the listings leave out.

If you want the look without the problems

The design language of the 6062, small case, star markers, full calendar, moonphase, shows up in legitimate dress watches and vintage-inspired homages from brands that publish real specifications. You get a moonphase that tracks the actual lunar month, serviceable parts, and something you can sell later. It is not the same as owning a 6062, but it is far closer to it than a replica with a painted moon.
