Frequently asked questions
What is the lug width of the SevenFriday P-Series P1/04?
The lug width of the SevenFriday P1/04 is 28mm. This measurement refers to the internal distance between the two lugs of the case and is decisive for the compatibility of aftermarket straps. It is essential to measure it with precision, from the internal edge of one lug to the other, to ensure proper insertion into the dedicated groove.
Which strap is recommended for the SevenFriday P1/04?
For the P1/04 we recommend an alligator strap with vegetable tanning in dark brown or anthracite tones, to enhance the industrial aesthetic of the case. Alternatively, a chrome-tanned smooth calf leather creates elegant contrasts, whilst for those preferring practicality a structured rubber strap or technical canvas NATO maintains coherence with the contemporary vocation of the model.
How do you change the strap on the SevenFriday P1/04?
Changing the strap requires a specific tool: a spring bar tool. Insert the tip of the tool into the lateral groove of the lug, apply gentle pressure to release the internal spring, and extract the old strap. The new 28mm strap is then inserted into the spring and pushed until completely engaged. We recommend having the operation performed by a professional watchmaker if you lack experience.
Is there an aftermarket strap compatible with the P1/04?
Yes, numerous aftermarket straps are available in the market for the 28mm lug width. It is essential to verify that they are specifically certified for this lug width, as it is a non-standard measurement. Milano Straps offers a curated collection of 28mm straps in various materials: alligator, calf, rubber, NATO and vegetable leather, selected for aesthetic harmony with the P-Series design.
What is the average lifespan of a leather strap for the P1/04?
The lifespan of a leather strap depends on daily use and maintenance. High-quality alligator or calf leather, with vegetable tanning, can remain in excellent condition for 3-5 years of regular use, with proper hygiene and protection from excessive moisture. The natural deterioration of leather is part of its beauty: the patina that develops over time testifies to the history of the watch and its owner.
