Strap for Tudor Black Bay 58 79012M

The Tudor Black Bay 58 79012M is equipped with a 20mm lug width. This measurement is proportionate to the case's compact 39mm diameter and is essential to verify before purchasing a compatible strap. Correct measurement is performed using a digital calliper between the two upper attachment points of the case.

For the 79012M, straps in cognac or chocolate brown alligator are recommended for chromatic harmony with the bronze patina, or vegetable-tanned calf in hazelnut tones for a cohesive vintage aesthetic. For those engaging in diving activities, black FKM rubber provides exceptional grip on wet skin. The choice depends on intended use and the personal tone of the oxidised bronze.

Changing the strap on the 79012M requires a spring bar tool: insert the tool's tip into the small lateral hole of the suspension spring on the first lug (the one not being removed), pressing downward to release tension. The spring will pop out. Repeat on the other side and remove the strap completely. Proceed in reverse with the new 20mm strap, ensuring both springs click into locked position.

Yes, any strap with a 20mm lug width is mechanically compatible. Aesthetic compatibility, however, depends on material and colour choice: calf or alligator creates elegant contrast with bronze, whilst NATO straps offer sporting versatility. Avoid undersized straps (18mm) or oversized ones (22mm), which compromise lug accommodation.

The lifespan of a natural leather strap on a Tudor Black Bay 58 ranges from 18 to 36 months, depending on frequency of wear, humidity exposure, and leather quality. Alligator tends to last longer due to the fibrous structure of the hide, whilst calf is more sensitive to prolonged moisture. Sun exposure accelerates ageing. Regular maintenance (drying after water exposure, monthly conditioning) significantly extends strap life.
