What a Black Bay 58 79030 Sells for in Bangkok — October 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).
Estimated price bands as of October 2026. The median is the WatchCharts market price for the 79030N (US$3,049 on 10 October 2026). The low end follows Loupe's US$2,687 fair market value and the April 2026 WatchCharts median of US$2,809 (5D Watches); the high end is the top of the Chrono24 complete-set range, about US$3,800. All are converted at ฿32.5/USD. They are US and international market figures, not Bangkok transaction records. The Black Bay 58 is among Tudor's most traded references in Thailand:
- Low ฿90,000 — 2019–2021 references, worn, no box
- Median ฿100,000 — Full-set 2022–2023 with TH warranty
- High ฿125,000 — NOS 2024+ with stickers
The 79030 is discontinued; the newer-generation Black Bay 58 trades at about US$4,300 pre-owned (WatchScanning).
Black Bay 58 Variants
| Reference | Colour | Median Bangkok 2026 |
|---|---|---|
| 79030N | Black bezel + dial | ฿100,000 |
| 79030B | Navy blue bezel + dial | ฿100,000 |
| 79012M | Bronze 39mm (Black Bay 58 Bronze) | ฿111,000 |
| 79250BM | Bronze 43mm (Black Bay Bronze, not a BB58) | ฿81,000 |
Blue and black trade at about the same price: Loupe puts the 79030B at US$2,657 and the 79030N at US$2,687. Earlier versions of this page claimed a ฿6,000–฿10,000 premium for blue; we found nothing to support it. The 79012M and 79250BM rows are the WatchCharts market values (US$3,416 and US$2,497) cited on our Black Bay family page, converted at ฿32.5/USD. Earlier versions of this page labelled the 79012M as the silver 925 (that is the 79010SG) and the 79250BM as a 39mm watch, and priced both well above those values.
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) |
| Material | 316L steel | 904L steel |

Black Bay 58 is the option for buyers seeking vintage-Submariner aesthetics in a 39mm package — close to the 5-digit Submariners of the 1990s — at about a quarter of the cost.
