The replica Blancpain 5200-0113-52a is a copy of the Fifty Fathoms Bathyscaphe Chronograph Flyback, a 43.6 mm dive chronograph with a ceramic case and a flyback chronograph movement. The reference number matters because it tells you which case finish, dial layout, and strap combination the watch should have, and that is the first thing to verify before you buy. If a listing shows the right reference but the wrong case material or bezel style, the number is decoration, not specification.
What the 5200-0113-52a Reference Describes
Blancpain reference numbers are built in blocks. The leading digits identify the model family, which in this case is the Bathyscaphe chronograph line. The middle group points to the dial and case variant, and the trailing code tells you how the watch leaves the factory: case material, finishing, and strap or bracelet type.
In practice this means a seller offering a replica Blancpain 5200-0113-52a should be showing you a Bathyscaphe chronograph with the matching case tone, the correct bezel insert, and the strap pairing the suffix implies. Photos that mix a steel case with a ceramic-only reference, or a bracelet with a strap reference, are the clearest warning sign that the listing is careless.
Core Specs to Compare Side by Side
Before reviewing photos, put the known specification next to the listing and check each line.
- Case diameter: the Bathyscaphe chronograph is a large watch at roughly 43.6 mm, and a replica that measures noticeably smaller or larger will not wear the same way.
- Case material: ceramic or treated steel, with the surface finish matching the reference.
- Water resistance rating: usually quoted at 300 m on the original, though a replica should never be trusted for diving regardless of what the caseback says.
- Bezel: a unidirectional rotating dive bezel with a sapphire or ceramic insert and clearly printed markings.
- Dial layout: subdials at the positions used by the Bathyscaphe chronograph, with a date window where the original places it.
- Movement type: an automatic flyback chronograph, not a quartz module or a non-flyback automatic.
Dial, Bezel, and Case Details That Show Quality
Most of the difference between an average replica and a high grade 1:1 replica Blancpain lives in small details rather than the overall silhouette.
Dial printing and hands
Look for crisp, evenly weighted print, a date wheel that sits flush in the window, and hands with clean edges and consistent lume fill. Crooked or blurry printing is visible at arm's length in person, even when photos hide it.
Bezel action and alignment
The bezel should rotate with defined clicks and stop with the triangle centered at 12. Misaligned inserts are among the most common flaws on cheaper Bathyscaphe copies.
Case finishing
Brushed and polished transitions should be sharp and straight. Rounded edges where there should be a crisp line, or a polished surface that should be brushed, are signs of a lower tier build.
The Flyback Function
Flyback means the chronograph can be restarted with a single push of the reset pusher while running, without stopping first. On a replica, test this carefully: press start, let it run, then press reset once and confirm the hand snaps back to zero and immediately resumes. If the movement requires a stop before reset, it is a standard chronograph wearing a flyback label.
Strap, Fit, and Wearability
The Bathyscaphe chronograph is a substantial watch, so wrist size matters. A 43.6 mm case with long lugs can overhang a small wrist, and the strap pairing changes the feel considerably. A rubber or sailcloth style strap sits the watch lower and suits the dive character, while a bracelet adds weight and visual presence. Check that the lug width matches the strap supplied, since mismatched spring bars and gaps at the lugs are easy to spot.
Questions to Ask Before Ordering
- Can you send real photos of the exact watch, not stock images?
- What movement is inside, and does it support flyback?
- What is the measured case diameter and lug width?
- Which strap or bracelet comes with this reference?
- What is the return policy if the watch arrives with a defect?
Common Mistakes Buyers Make
The most frequent error is buying on price alone and accepting a watch whose reference number does not match its parts. The second is assuming water resistance transfers from the original: a replica caseback engraving is not a pressure test, so keep replica watches away from swimming and diving. The third is ignoring the movement, which is what determines whether the chronograph feels solid or fragile in daily use.
Short Answer
Treat the replica Blancpain 5200-0113-52a as a specification problem before a looks problem. Confirm the case material, diameter, bezel, dial layout, strap pairing, and flyback movement all match the reference, then judge finishing from real photos. Doing the checks in that order filters out most disappointing purchases.
