Tudor Black Bay M79830RB-0001

58 Steel/Blue 39mm · 41mm · Automatic · 200m WR

Tudor was founded by Hans Wilsdorf (Rolex's founder) in 1926 to offer Rolex quality at more accessible prices. For decades, Tudor shared Rolex cases and bracelets but used third-party movements. The brand's modern renaissance began in 2012 with the Heritage Black Bay, and today Tudor is among the hottest value propositions in luxury watches.

Trading near its retail price on the secondary market, this reference offers good value for buyers. The parity between retail and market pricing suggests balanced supply and demand, making it accessible without excessive premiums or lengthy dealer waitlists.

Exclusive Analysis

True Cost of Ownership

Understanding the true cost of owning a luxury watch requires looking beyond the purchase price. Our cost-of-ownership model calculates the annual net expense of keeping the Tudor Black Bay M79830RB-0001 on your wrist, factoring in three key components.

First, depreciation: based on historical pricing data for this reference and similar Tudor models, we estimate annual value change at 2%. This low depreciation rate means the watch holds its value exceptionally well compared to most luxury goods. Second, servicing: Tudor recommends periodic maintenance to ensure accuracy and water resistance. We amortize the estimated service cost across the recommended interval, arriving at $80 per year. Third, insurance: at approximately 1.5% of market value, annual insurance costs $56 to protect against theft, loss, or accidental damage.

Combining these factors yields a net annual cost of $210. That's roughly $0.58 per day — less than a daily cup of coffee.

Buying Guide: Tudor Black Bay

What is a Dive Watch?

Originally designed for professional underwater use, modern dive watches are equally at home on a desk as they are at depth. The rotating bezel tracks elapsed time underwater, while the high water resistance and luminous markers ensure readability in low-light conditions.

What to Look For in a Dive Watch

Key specifications for a dive watch include water resistance (minimum 200m for ISO 6425 certification), unidirectional rotating bezel, luminous hands and indices, screw-down crown, and robust bracelet with dive extension. Higher-end models feature helium escape valves for saturation diving.

When and Where to Wear

Dive watches are the most versatile luxury watch category. They pair equally well with a suit, casual wear, or technical gear. The sport-luxury aesthetic makes them appropriate for virtually any situation, which is why models like the Submariner and Seamaster are among the best-selling luxury watches globally.

Buying a Tudor: What You Need to Know

Tudor watches are readily available at Rolex authorized dealers and Tudor boutiques. Pricing is relatively stable with occasional modest discounts. The Black Bay line offers the closest alternative to Rolex quality and design language at roughly one-third the price — making it the ideal entry into luxury watchmaking.

Tudor Movement & Quality

Tudor now manufactures its own movements, including the MT5602 (time-only, 70hr power reserve) and MT5813 (chronograph, developed with Breitling). These movements are COSC-certified and offer specifications comparable to watches costing 2-3x more. The Pelagos features an in-house calibre with silicon hairspring.

Service & Maintenance

Tudor recommends servicing every 10 years (same as Rolex). Service costs are substantially lower at $400-$600 for standard models. The 5-year warranty with registration is generous for the price segment and provides peace of mind.

Tudor Resale Value

Tudor watches hold value well relative to their price point, typically retaining 70-85% of retail value. The Black Bay 58 and Pelagos models hold value best. While Tudor won't appreciate like Rolex, the low entry price and strong retention make the cost of ownership remarkably low.
