Black Bay 41 METAS

The Tudor Black Bay 41 METAS marks a major milestone for the Black Bay line, introducing Master Chronometer certification to the collection for the first time. This watch takes the classic Black Bay aesthetic—born from Tudor’s dive heritage—and elevates it with cutting-edge precision and magnetic resistance, making it especially appealing to those seeking both tradition and technical innovation. With its 41mm stainless steel case and signature snowflake hands, it balances presence and wearability, offering a versatile option for daily use and collection rotation alike.

Reference 79910 is the key identifier for this model, setting it apart from previous Black Bay 41 versions that lacked METAS certification and used different calibers. Inside, the in-house MT5602-U movement delivers 70 hours of power reserve and boasts METAS Master Chronometer status, meaning it meets stringent Swiss standards for accuracy, antimagnetism (up to 15,000 gauss), and water resistance (200m). Earlier Black Bay 41s, like the 79230 series, do not feature these upgrades, which is reflected in both pricing and desirability.

Price variation comes down to condition, bracelet options (steel bracelet versus hybrid rubber/leather), and whether the full set—box, papers, METAS certificate—is included. The METAS-certified Black Bay 41 is still relatively new to the market, so supply is tight and premiums are common, especially for unworn examples. If you value chronometric performance and want the most technically advanced Black Bay to date, this is the reference to target.
