Frequently asked questions
What is the lug width of the Tudor Heritage Black Bay Fifty-Eight 79620T-0009?
The lug width is 22mm. This is the linear distance between the two attachment holes for the original strap pins. It is essential to measure this precisely using a digital calliper to ensure complete compatibility with aftermarket straps.
What is the best strap for the Tudor Heritage 79620T-0009?
It depends on intended use. For diving operations, a structured rubber strap with natural elastomer guarantees maximum grip and durability. For urban contexts with occasional water contact, a hand-finished alligator in platinum grey or a premium NATO in nylon cordura offers aesthetic and practical versatility. Vegetable-tanned calf leather suits those who prioritise tactile sensitivity in protected environments.
How do I change the strap on the Tudor Heritage 79620T-0009?
Strap replacement requires a spring bar tool (lug-pin lever). Insert the flat tip of the lever under one of the case lugs, apply gentle downward pressure to release the internal spring, and extract the pin. Repeat on the opposite side. Insert the new strap's pins into the same holes, ensuring the spring clicks into position correctly. Check visual alignment before and after installation.
What is the average lifespan of a leather strap for the Tudor Heritage 79620T-0009?
An alligator or vegetable-tanned calf strap, subjected to moderate use (daily wear but not continuous), has a lifespan of 3–5 years before requiring regeneration treatments (conditioning, microfracture closure). With regular maintenance (soft brushing, air-drying after water exposure), this extends to 7 years. NATO straps have superior durability, exceeding 10 years, if washed periodically.
Can I use the Tudor Heritage 79620T-0009 underwater with an aftermarket strap?
Yes, provided you select appropriate materials. Structured rubber and nylon cordura NATO straps maintain water-repellent and grip properties even in immersion. Leather straps (alligator, calf) tolerate occasional bathing and quick rinsing, but not prolonged diving—water penetrates the fibres, causing deterioration. For intensive underwater use, opt for rubber or NATO.
