Strap for Heritage Chrono Black / Bracelet

The Tudor Heritage 70330N-0005 features a 22mm lug width. This measurement refers to the space between the case terminals where the strap attaches. To verify the width, simply measure the distance between the attachment points using a digital calliper: 22mm is the exact dimension that ensures full compatibility and installation without mechanical play.

For the 70330N-0005, we recommend a strap in alligator leather with vegetable tanning, in tobacco brown or burgundy. Alligator leather develops a natural patina that dialogues perfectly with the stainless steel case, creating a rare aesthetic harmony. Alternatively, superior quality calf leather offers a more uniform finish and elegant ageing over time.

To change the strap, you must remove the spring bars that connect the strap to the lugs. Use a dedicated spring bar tool to compress the retainers and slide the pins inward. Once removed, insert the new strap and secure the spring bars with firm pressure until you hear a distinct click. The operation requires delicacy to avoid scratching the case.

Yes, any commercially available strap with a 22mm lug width is compatible with the Tudor Heritage 70330N-0005. The important thing is to verify that the strap has been specifically manufactured for this width, to ensure that the spring bars sit correctly without excessive movement or anomalous friction.

A quality leather strap with vegetable tanning lasts on average 3-5 years before requiring replacement, depending on intensity of use and care. Leather dyed with vegetable methods develops a fascinating patina over time, although the fibre structure gradually thins. Prolonged exposure to perspiration, intense humidity and direct sunlight accelerates ageing. The standard warranty is 18 months on quality artisanal straps.
