What a Black Bay 58 79030 Clears for in Bangkok — June 2026
The Tudor Black Bay 58 79030 launched in 2018 and the global watch community quickly named it the "best value diver". Tudor moved from ETA base (rosref 79220) to MT5402 in-house caliber in the 79030, with a 39mm case (down from 41mm of the regular Black Bay).
Thai Watch Market drawn from our work in Bangkok's pre-owned market Jan–May 2026 — Black Bay 58 is Tudor's highest-turnover reference in Thailand:
- Low ฿115,000 — 2019–2021 references, worn, no box
- Median ฿125,000 — Full-set 2022–2023 with TH warranty
- High ฿138,000 — NOS 2024+ with stickers
Black Bay 58 Variants
| Reference | Colour | Median Bangkok 2026 |
|---|---|---|
| 79030N | Black bezel + dial | ฿122,000 |
| 79030B | Navy blue bezel + dial | ฿128,000 |
| 79012M | Silver "925" | ฿165,000 |
| 79250BM | Bronze 39mm | ฿138,000 |
Blue (79030B) trades ฿6,000–฿10,000 above Black (79030N) in Thailand because the blue version launched two years later (2020 vs 2018), production volume runs lower, and navy pairs naturally with formal attire.
Tudor Black Bay 58 vs Rolex Submariner
The most-asked question in the Thai pre-owned market:
| Feature | Tudor BB58 79030 | Rolex Submariner 126610LN |
|---|---|---|
| Size | 39mm | 41mm |
| Thickness | 11.9mm | 12.5mm |
| Water resistance | 200m | 300m |
| Caliber | MT5402 (70h) | 3235 (70h) |
