FAQ

What is the lug width of the Zenith Revival 03.A384.400/385.M385?

The Zenith Revival 03.A384.400/385.M385 is fitted with a 20mm lug width. This measurement, called lug width, represents the internal distance between the two metal lugs where the strap is attached. It is essential to verify this dimension before purchasing an aftermarket strap to ensure perfect compatibility.

Which strap should I choose for the Zenith Revival 03.A384.400/385.M385?

For the Revival we recommend alligator in dark brown or black tones, or vegetable-tanned chromexcel calf in cognac. Alligator imparts formal elegance while maintaining a sporty spirit, while calf leather develops natural patina over time. NATO nylon remains a practical option for everyday use. The choice depends on your use: formal (alligator), versatile (calf), or sporty (NATO/rubber).

How do I change the strap on the Zenith Revival 03.A384.400/385.M385?

Strap replacement on the Revival is done using a dedicated tool (spring bar tool) to compress the small elastic pins located at the lug ends. The strap is removed by sliding outward after releasing the pins. The operation takes just a few minutes and requires no special skills. If you prefer to have a professional handle it, Milano Straps provides support and can coordinate the service.
