Entry to the Grand Prix d'Horlogerie de Genève is voluntary and made by the brand. An entry is a watch registered for that year's competition, not a jury verdict, and several large houses including Rolex, Patek Philippe and Omega do not take part at all.
At 39mm with an in-house movement and METAS certification, this is widely cited as the strongest value proposition in the sub-$4,000 dive watch market.
The Homme category at GPHG 2018 held 21 entries. These are the other 20.
Pre-owned watches trade across a wide condition spectrum. These ranges are typical for the secondary market.

The Black Bay 58 is Tudor's strongest secondary market performer; 39mm size and in-house movement make it compelling relative to its price, keeping used demand robust.
Editorial estimate, 2026 Q2. Actual prices vary by condition, date, and box/papers status.
Manufactured in-house by Tudor; parts are not independently distributed but Tudor service centers are widespread enough to keep wait times reasonable.
The Black Bay 58 is Tudor's most replicated current reference. The 39mm size and navy dial variant are the primary targets. Quality of the in-house movement and bracelet finishing are the key authentication points.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| dial | Snowflake hand and dial color matching | The navy blue dial has a specific deep blue that is consistent under different lighting conditions; the snowflake hour hand has the wide-paddle lume block | Dial that appears too bright or too dark compared to known examples; snowflake hour hand with incorrect lume block proportions |
| hands | Snowflake hand lume fill quality | The wide snowflake lume paddle fills the hand cavity cleanly with Super-LumiNova; tube edges align with hand edges; all lume color matches across hour and minute hands | Lume overflow or recessed lume below the hand edges; lume color mismatch between the hour and minute hands; lume fill that is uneven across the snowflake paddle |
| case | Tudor shield logo and surface finishing | Tudor shield on crown is sharply defined with correct proportions; case sides brushed; lugs with correct taper; 39mm measured lug-to-lug | Soft or misshapen Tudor shield on crown; case that has been polished uniformly removing the brushed-to-polished transition; lug geometry inconsistent with known production |
| movement | MT5402 in-house caliber identification | The BB58 uses Cal. MT5402; 70-hour power reserve; COSC chronometer certified; silicon balance spring; bidirectional rotor; visible through caseback | Non-Tudor movement; ETA movement in a stated post-2018 BB58; absence of silicon spring or COSC certification specification |
| bracelet | Rivet-style bracelet end-link fit | The rivet bracelet seats flush against the case horn with no lateral movement; rivet heads are correctly domed; center links brushed, outer links have correct finishing | Visible gap between end link and case horn; rivet heads that appear flat or have incorrect doming; bracelet that rattles laterally when held still |
| caseback | Solid caseback and engravings | Solid caseback with TUDOR shield engraved at center; reference M79030N and serial number in correct Tudor typeface; water-resistant rating stamped | Display caseback on a stated standard BB58 (should be solid); engraving in incorrect Tudor typeface; serial number absent or inconsistent with known Tudor production format |
The Black Bay 58 is among the most-faked sport watches under $5,000 and the bronze dial variant has attracted particularly high replica volume. The snowflake hand profile and gilt text are the fastest field tells.
