Authentication
The caseback is titanium, not bronze, specifically to avoid skin contact with the bronze case; a bronze caseback on this reference is inconsistent with factory spec.
Known issues in the market
- Genuine bronze cases patina naturally over weeks and months of wear; be cautious of a case represented as worn but showing no oxidation at all, or an artificially and unevenly aged finish.
- This reference has no date window and no chronograph; a date aperture or sub-dials on a watch sold as this reference indicates a different Pilot Type 20 model.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| case | Bronze case with titanium caseback | Rough satin-finished bronze case (case, crown, and pushers), titanium caseback engraved with Zenith’s flying-instrument logo and Blériot’s aircraft | Bronze or steel caseback instead of titanium; case material inconsistent with bronze (no capacity to patina) |
| dial | Matte black dial, no date | Large Arabic numerals in slightly cream-toned Super-LumiNova, golden cathedral-style hands, no date window disrupting dial symmetry | Date window present; numerals or hands inconsistent with the cathedral-and-Arabic-numeral pilot style |
| movement | Elite 679 in-house caliber | Elite 679 self-winding 3-hand movement (no chronograph, no date module), visible only via service access since this reference has a solid caseback | Sellita SW200 or ETA 2824 substitute movement; chronograph sub-dials or date complication inconsistent with this reference |
Common legitimate replacements
- Original oily nubuck leather strap with black rubber lining and titanium buckle; this is the factory-only strap option for this reference.
