The Tudor Black Bay is one of the most strap-friendly watches you can own. Its vintage-inspired case and slab-sided lugs suit leather, rubber and steel equally well, and swapping the band completely changes the watch’s character — from weekend diver to office companion in a couple of minutes. Whether you have a Black Bay, Black Bay 58, Pelagos or the 1958 GMT, here is how to choose the right replacement in each material, how to fit it, and the one sizing detail Tudor owners need to get right.
Steel bracelet: the everyday upgrade
A steel bracelet is the most versatile Black Bay option — dressy enough for the office, tough enough for daily wear, and heavy enough to balance the watch nicely on the wrist. Our aftermarket 316L stainless steel bracelet comes in silver or black at 22mm, with removable links you can adjust at home rather than paying a jeweller. It is cut to echo the classic three-link Black Bay look — brushed outer links with a subtle polished bevel — without the cost of the original.
316L is the marine-grade steel used on most quality bracelets: corrosion-resistant, easy to keep clean, and built to shrug off salt water and daily knocks. Because the links are solid rather than hollow, the bracelet has the dense, planted feel Black Bay owners expect.
Rubber: dive-ready and light
For summer, water and sport, FKM rubber is the natural choice — it resists heat, chlorine, salt and sweat, wipes clean in seconds, and shrugs off UV without cracking or fading. It also drops a noticeable amount of weight versus steel, which makes the Black Bay disappear on the wrist during activity.
The detail that matters most on a Black Bay is the curved end: a well-made rubber strap is shaped to meet the case with no gap, so it looks integrated rather than bolted on. A straight-end strap will leave an unsightly gap at the lugs. Our FKM curved-end strap for the Black Bay 1958 GMT pairs that seamless fit with a secure folding buckle and comes in several colours to match dial and bezel.
Leather: dress it down or up
Leather is what turns the Black Bay into a dress-adjacent watch. It warms up the vintage dial and lug shape and works especially well on the Black Bay 58 and 1958 GMT, whose smaller cases suit a more refined band. A stitched leather strap takes the watch comfortably from jeans to a jacket, and over time it develops a personal patina that many owners consider part of the appeal.
Our replacement leather band is cut for a 22mm fit and finished for daily wear. The one rule with leather is to keep it away from prolonged water — for beach and pool days, switch to rubber and keep the leather for dry-land duty.
How to fit a Black Bay strap
Changing a Black Bay band at home takes a spring-bar tool and a few minutes. Lay the watch face-down on a soft cloth to protect the case, slide the forked end of the tool between the strap and the lug, compress the spring bar until one side releases, and lift the strap away. To fit the new band, seat one end of the spring bar in its lug hole, compress the other end and guide it into the opposite hole until it clicks. Always tug both sides to confirm the bars are locked before wearing the watch. If your strap uses a folding clasp, set the fit using the clasp’s adjustment holes rather than forcing the band.
Sizing: 22mm, curved end, and the 2024 change
Most Black Bay models take a 22mm strap, but two details catch people out. First, many rubber and steel options use a curved end to sit flush against the case — a straight-end band will leave a gap, so always check that a replacement is shaped for the Black Bay. Second, Tudor revised the bracelet and end-link fitment on 2024-onward models, so our steel bracelet is cut for pre-2024 Black Bay references. If you are unsure of your lug width or which generation you own, check our lug width guide before ordering.
Caring for your Tudor strap
Each material asks for a little different care. Rinse rubber and steel with warm water after salt, chlorine or sweat, and brush between steel links occasionally to lift grime. Keep leather dry, wipe it with a slightly damp cloth when needed, and let it breathe between wears. A few minutes of upkeep keeps any of these bands looking sharp for years.

Frequently asked questions
What size strap does a Tudor Black Bay take?
Most Black Bay models use a 22mm lug width. Many rubber and steel options are curved to sit flush against the case, so choose an end shaped for the Black Bay rather than a straight-end band.
Do aftermarket bracelets fit the 2024 Black Bay?
Tudor changed the bracelet and end-link fitment on 2024-onward Black Bay models. Our steel bracelet is cut for pre-2024 references, so confirm which generation you own before ordering.
Which strap material is best for a Black Bay?
It depends on use. Rubber is best for water, sport and hot weather; steel is the versatile all-rounder; leather dresses the watch up for the office or evening. Because swaps take only minutes, many owners keep two or three and change to suit the day.
Can I change a Tudor strap myself?
Yes. With a spring-bar tool and a soft cloth to protect the case, most people can swap a Black Bay strap in a few minutes. Always check both spring bars are locked before wearing the watch.
