Frequently asked questions
What is the lug width of the Tudor Black Bay 79733N-0005?
The lug width of the Tudor Black Bay 79733N-0005 is 22mm. This measurement represents the distance between the lower attachment points of the case. It is essential to measure the lug width correctly using a digital calliper: remove the original strap, position the tool between the inner edges of both lugs, and read the measurement. For the 79733N-0005, the result will invariably be 22mm, ensuring full compatibility with all 22mm strap options available on Milano Straps.
Which strap is most suitable for the Tudor Black Bay 79733N-0005?
The choice depends on intended use and personal aesthetic preference. Alligator represents the classical and aristocratic solution, featuring an almost imperceptible natural grain and a patina that develops over time. Calf leather with pebble grain offers a more pronounced texture, adding dynamism whilst maintaining formality. Traditional vegetable tanning provides an ethical and authentic alternative, with pronounced character and tactile evolution with age. For intensive marine use, vulcanised FKM rubber ensures resistance to salt water. For casual-sporty versatility, a woven NATO nylon strap offers reversibility and practical durability.
How do I change the strap on my Tudor Black Bay 79733N-0005?
To change the strap, you must remove the spring bars connecting the strap to the case lugs. Proceed as follows: position the watch face-down on a soft cloth, use a spring bar removal tool (typically a small bifurcated lever) to gently press inward one of the pins, creating sufficient space to slide out the strap. Repeat from the opposite side. Once the old strap is removed, align the new strap's spring bars with the lugs and gently push until you hear a click. Avoid excessive force: Tudor spring bars are standard and should slide without resistance.
Can I use an aftermarket strap compatible with the Tudor Black Bay 79733N-0005?
Absolutely. The Tudor Black Bay 79733N-0005 features a standard 22mm lug width, which is widely supported by the aftermarket strap market. Any strap with 22mm lugs is mechanically compatible. Milano Straps offers a complete collection of customizable 22mm straps in material, colour, length, and details (initials, stitching thread). The Casati Milano atelier can furthermore create entirely bespoke straps, with personal consultation on available leathers and an 18-month guarantee.
How long does a leather strap last on the Tudor Black Bay 79733N-0005?
Leather strap longevity depends on material, frequency of use, and environmental conditions. A quality alligator strap with traditional tanning can last 5-10 years with moderate use and appropriate maintenance (regular cleaning, avoiding prolonged excessive moisture). Calf leather has similar longevity, approximately 4-8 years. Vegetable-tanned leather, although naturally more robust, evolves with time; with care it can remain functional for 7-10 years. Rubber straps have shorter useful life, typically 2-4 years, as elastomer degrades through UV exposure and oxidation. Milano Straps offers an 18-month guarantee on personalised straps and recommends periodic maintenance to extend longevity.
