Short answer
Pick the original if you want the flyback function, the 300 m water rating, and a movement a watchmaker can service. Pick a top-tier replica at USD 800 to 1,100 if you want the 43.6 mm Bathyscaphe look on a budget and accept two limits: no true flyback, no parts supply.
How to Identify a Replica Blancpain 5200-0113-52A Watch
What the 5200 reference is
The 5200 line is the Blancpain Fifty Fathoms Bathyscaphe Chronographe Flyback. Most 5200 references share one case: 43.6 mm wide, about 14.9 mm thick, ceramic on some variants and steel on others, ceramic bezel insert, 300 m water resistance. Movement is the Blancpain F385, an automatic derived from the Frederic Piguet 1185 architecture: 28,800 vph, 50 hour power reserve, flyback. The "52A" tail is a strap code used across the Bathyscaphe range. Dial color and case material for the 0113 variant should be confirmed on the Blancpain catalog page before you buy.

Where replicas land close
- Case and lugs: better builds sit within 0.2 to 0.3 mm of the original 43.6 mm width.
- Dial layout: three counters and a date window near 4:30. Print and applied markers read correct at arm's length.
- Strap: sailcloth and NATO options in matching widths.
- Crystal: sapphire on tier 2 and tier 3 builds.
Where replicas fail
- Movement: tier 2 and tier 3 replicas use the Valjoux 7750 or a clone. The 7750 is a cam and lever chronograph. Flyback needs a different mechanism. Press the lower pusher while the chronograph runs and the movement stops or the hands jump.
- Case material: the original uses zirconium oxide ceramic. Many replicas use steel with a PVD or DLC coat. One scratch shows grey metal under the black.
- Weight: coated steel cases run 20 to 40 g heavier than ceramic.
- Water resistance: replica listings claim 300 m. Gaskets arrive dry or missing on some units. No pressure test exists. Do not swim.
- Finishing: brushing on the lugs and caseback is coarser. Bezel numerals are printed, not ceramic filled, on tiers 1 and 2.
- Lume: charge time and glow duration run short of Super-LumiNova.
- Service: no parts supply. A broken replica becomes scrap. Blancpain service runs on a 5 to 7 year interval.
Three options
- Best pick for most buyers: a top-tier replica at USD 800 to 1,100. 7750 base, ceramic or DLC case choice, sapphire crystal, correct dimensions. Buy from a seller who posts a movement photo and offers a return window.
- Budget pick: USD 300 to 500. Plated case, mineral or low-grade sapphire, rough pusher feel.
- Original: list price sits in the USD 17,000 to 20,000 band, pre-owned lower. You get the flyback, the ceramic case, the 300 m rating, and a serviceable calibre.
