Start with the original
Jaeger-LeCoultre released the Master Compressor Extreme Lab 2 in 2010. The watch took the sports watch prize at the Grand Prix d'Horlogerie de Genève that year. Retail was five figures. The earlier Extreme Lab 1 arrived in 2007 as a concept piece with a titanium case and no lubricants in the movement.
The Extreme Lab 2 uses a grade 5 titanium case. Listed diameter is 46.8 mm. The movement is an in-house automatic chronograph, Calibre 780, with a function selector built into the crown. The selector moves the crown between winding, date setting and time setting. The pushers sit under a locking collar. Confirm the power reserve figure with Jaeger-LeCoultre before you compare spec sheets, because published numbers differ by source.

What "cheap" means for this model
Replica versions of the Extreme Lab 2 sell from about $80 to $500. The price tracks the movement and the case, not the dial print. Under $150 you get quartz or a low-grade Chinese automatic. The sub-dials are either glued on or driven by a decorative gear train. The function selector becomes a ring that turns and does nothing. The case is 316L steel with a grey coating. It feels heavier on the wrist than the titanium original.
Parameters to verify
- Movement. Ask for the calibre name and a photo through the caseback. A closed caseback on a low-price listing hides a quartz module.
- Case size. 46.8 mm is large. A listing that says 42 mm is a different watch with a similar dial.
- Weight. Titanium is light. Ask for a photo of the watch on a scale in grams.
- Dial layout. Count the hands and note where each one sits. Match the layout to official photos. Mismatched sub-dial positions signal a stock movement.
- Crystal. Sapphire on the original. Mineral glass scratches within months.
- Lume. Applied Super-LumiNova on the original. Paint on most cheap units. Paint fades and reads uneven.
- Crown and pushers. Screw-down crown and locking pushers on the original. On a cheap replica the crown pulls straight out with no thread.
- Water resistance. Claims on replicas are unverified. Do not swim with one.
Price bands
- $80 to $150: quartz or basic automatic, mineral glass, steel case, decorative pushers.
- $150 to $300: automatic clone movement, sapphire sometimes, better dial print, selector still non-functional.
- $300 to $500: closer case finishing, working chronograph from a 7750 clone, case still steel.
Grade 5 titanium at these prices is rare. Ask for a material statement and a scale photo, or buy from a seller with a return window.

Pitfalls
- Listings that use press images instead of photos of the unit you will receive.
- "Swiss made" text on a $120 watch.
- Sellers who refuse a QC photo of the caseback, crown and clasp.
- Spec tables that list 46.8 mm but show photos of a smaller case.
- Payment by wire or crypto with no refund path.
- "1:1" or "super clone" claims on this model. The crown selector is the hardest part to copy, and a cheap build will not copy it.
- Strap photos that show alligator but ship polyurethane.
Ask the seller
- Dated photos of the actual watch with a ruler next to the case.
- A scale reading in grams.
- Movement name and a caseback photo.
- Strap material and lug width in mm.
- Return window, and who pays return shipping.
- Serial and model markings, so you can compare against reference photos.
Shipping and risk
Replica shipments can be held at customs. With many sellers the loss falls on the buyer. Get the risk terms in writing before payment. Keep the payment record and the chat log. If the seller will not put terms in writing, treat the order as a loss.
Bottom line
A cheap Extreme Lab 2 replica buys the look of a 46.8 mm titanium chronograph and little else. Buy it as a costume piece at a price you can lose. Do not buy it as a substitute for the real watch, and do not expect the function selector, the titanium case or the water resistance to survive inspection.
