Yes. The Tudor Black Bay 41 uses a 16mm / 18mm / 20mm / 22mm lug width and is fully compatible with Smartlet One. Smartlet One replaces the standard strap via the spring-bar system and positions your smartwatch on the same wrist. The Tudor Black Bay 41 requires no modification, no drilling, and no adhesive. The setup is fully reversible in seconds and your Tudor can be worn independently at any time by reinstalling its original strap.

No. Smartlet One makes no contact with the Tudor Black Bay 41 case, bezel, or crystal. It replaces the strap only, using the existing spring-bar slots. The module is manufactured in 316L stainless steel or titanium with polished and brushed finishing, and all contact points are non-abrasive. Your Tudor Black Bay 41 is protected throughout. The system is fully reversible and leaves no trace.

The Tudor Black Bay 41 with its 16mm / 18mm / 20mm / 22mm lug width is compatible with the full Smartlet range. All smartwatch sensors remain operational when worn via Smartlet.
