Over the past five years, the replica watch industry has made tremendous progress in materials, finishing, and—most importantly—movement reliability. Unlike the unreliable calibers used a decade ago, today’s super clones feature highly refined mechanisms, thanks to advancements from China’s top movement factories: Dandong, Shanghai, and Hangzhou.

Let’s break down the best (and worst) movements in today’s market.

1. Dandong Movements – The Gold Standard

Dandong has developed some of the most stable and sought-after movements in replicas, including:

✅ Dandong 4130 (Best Chronograph Movement)

  • Originally used by Noob Factory, now adopted by Clean, VS, BT, and New Noob.

  • Most reliable chronograph in replicas—durable, accurate, and smooth.

  • Powers Daytona models from top factories.


✅ Dandong 4131 (The New Benchmark)

  • Used by VS & Clean in their latest Daytonas.

  • An upgraded version of the 4130, maintaining the same stability.


✅ Dandong 3235 (Exclusive to VS Factory)

  • Also called "VS 3235" or "Custom VS 3235".

  • Found in VS Datejust, Submariner 41mm, Yacht-Master, Sea-Dweller, and Oyster Perpetual.

  • 72-hour power reserve—best clone 3235 on the market.


❌ Avoid: Dandong 938 & 925

  • 938 (JLC Master Ultra Thin Q1372520) – Prone to failure (used by AZ & ZF).

  • 925 (JLC Moon Phase 1368430) – Less stable than a Dandong 7750 (used by APS & ZF).


✅ SL6000 (IWC Portuguese 7 Days & Big Pilot)

  • Used by ZF & AZ, offers 50+ hours power reserve.

  • Highly recommended for IWC fans.


✅ VS Factory’s 8500 & 8900 (Omega Replicas)

  • Powers VS’s Omega Seamaster 150m & 600m—key to their global reputation.


✅ P.9000 (Panerai Exclusive by VS)

  • Alongside the 8500, this movement helped establish VS as a top-tier factory.


2. Shanghai Movements – A Mixed Bag

✅ SH3135 (Second Generation – Reliable)

  • Improved stability, comparable to Dandong 3135.

  • Used in older Submariner 40mm models.
