What is a replica 1735 Grande Complication?

A replica 1735 Grande Complication is a copy of the Patek Philippe reference 1735, the platinum wristwatch the brand released in 1991 for its 150th anniversary. The copy reproduces the case and dial layout. It does not reproduce the mechanics, and no clone factory has built a working minute repeater, split-seconds chronograph, and perpetual calendar inside one movement.

The original sits in a small group of watches that collectors call grand complications. Production numbers were tiny, and sources differ on the exact count, which is why the reference appears at auction rather than in a normal catalog.

Why the original is hard to copy

Patek Philippe built the 1735 as a showcase of what a mechanical wristwatch can do. The movement drives a minute repeater, a split-seconds chronograph, and a perpetual calendar with moon phases, and each function needs its own set of parts.

A repeater alone requires two gongs, a hammer set, and a rack that reads the time to the minute. A split-seconds chronograph adds a second center hand with a clamp and an isolator. Assembling those parts takes a watchmaker days, and that is before the calendar work begins.

What replica versions deliver

Listings for a 1735 replica fall into three groups. Only the third group comes with an honest description of what the buyer gets.

• Decorative copies. A quartz movement behind a dial with printed subdials. Nothing moves except the main hands.
• Semi-functional copies. An automatic or hand-wound movement with a running seconds hand and a date, dressed to look like a perpetual calendar.
• Homage builds. Unbranded watches with a similar case shape and dial layout, sold without a Patek Philippe logo.

None of these strike, split, or track leap years. A listing that promises a working minute repeater at a replica price is describing a watch that does not exist.

How to inspect a replica 1735 before you buy

Work through the same checks a watchmaker would use on any complicated piece. Photos hide more than they show, so ask for video of the watch running.

Case and proportions

The reference 1735 uses a compact case that suits its era. Many replicas stretch the case to 40mm or more, which throws off the dial balance and makes the subdials look crowded.

Dial, subdials, and moon phase

Ask which subdials move. On most copies the calendar and moon phase are printed or stamped, so the moon disc never advances. Compare the layout against an auction catalog photo of the real reference before you trust a seller's rendering.

Movement and function

Request a clear photo of the movement through the caseback, plus the movement name. A seller who cannot name the caliber is selling a case with a mystery inside. Pushers that do nothing are a sign the chronograph is decorative.

Finish, weight, and engraving

Platinum is dense. A steel case with a platinum finish feels lighter than the real thing, and the difference is easy to notice in hand. Look at the sharpness of any engraving on the caseback. Soft or shallow lettering tells you the case came from a low-cost mold.

• Ask for a running video with the subdials in frame.
• Confirm whether each subdial moves or is decorative.
• Check that the pushers and crown do something.
• Compare case thickness, not just diameter, to the reference.
• Read the return policy before you pay.

Price bands in the replica market

Asking prices cluster into three bands, and the band tells you what to expect before you open the case.

• Under $80. Quartz, decorative subdials, base metal case.
• $150 to $400. Automatic movement, working date, better finishing, closer proportions.
• $500 and up. Top-tier clone cases and movements. Still no repeater, no split seconds, no true perpetual calendar.

If a seller quotes four figures for a 1735 replica with full complications, the phrase is marketing. The parts alone would cost more than the asking price.

Legal and practical risks

Counterfeit watches that carry a protected brand name are illegal to import in the US and most of Europe. Customs officers seize packages, and the buyer loses both the watch and the money.

• Customs seizure with no refund from the seller.
• No manufacturer warranty and no spare parts.
• Repair shops decline work on counterfeit movements.
• Resale value close to zero.

Water resistance claims on any replica deserve doubt. A gasket that costs cents will not survive a swim.

Questions buyers ask

Does a working replica of the 1735 exist?

No. A watch that repeats the time, splits seconds, and runs a perpetual calendar at replica prices is not on the market. Copies show the look, not the functions.

How much does a replica 1735 cost?

Most listings sit between $60 and $400. Price tracks the movement, the case material, and the quality of the dial printing, not the number of complications shown on the dial.

Is the reference 1735 still made?

No. Patek Philippe built it for the 150th anniversary in 1991, and sources differ on the exact production count. The brand moved on to other anniversary grand complications after that.

Can a replica 1735 be serviced?

Independent watchmakers can sometimes swap a movement or a gasket. Few will touch decorative subdial assemblies, and parts for clone calibers are scarce.

What to do with this information

Treat a replica 1735 as a costume piece and judge it on looks, fit, and price. If you want the real functions, save for a watch with a documented repeater or chronograph from a maker that services its own movements. There is no shortcut around the engineering.
