Frequently asked questions

What is the lug width of the Furlan Marri Chronograph Flyback 3177-A?

The lug width of the Furlan Marri Chronograph Flyback 3177-A is 20mm. This width has been calculated to achieve harmonic proportions with the 38mm case diameter. To verify correct measurement, position a ruler perpendicular to the lug and measure the internal distance between the two attachment holes.

Which strap is most suitable for the Furlan Marri Chronograph Flyback 3177-A?

The Chronograph Flyback 3177-A pairs beautifully with natural alligator, vegetable-tanned calf leather, and technical sports rubber straps. Alligator, with its distinctive texture, creates sophisticated contrast with the stainless steel case. Vegetable-tanned calf develops progressive patina that enhances the timepiece's sporty character. Rubber and NATO straps provide functional versatility whilst maintaining visual clarity.

How do I change the strap on the Furlan Marri Chronograph Flyback 3177-A?

Position the watch on a stable support. Use a dedicated spring bar tool to access the lug attachment mechanism. Insert the tool tip into the lateral hole of the attachment and apply gentle pressure until the spring is released. Remove the old lug and insert the new one, ensuring that the retaining springs are perfectly anchored at both attachment points. Verify that the strap is symmetrically positioned before closing.

Can I use an aftermarket compatible strap with the Furlan Marri Chronograph Flyback 3177-A?

Yes. The 3177-A, with its 20mm stainless steel lug width, is fully compatible with certified quality aftermarket straps. Milano Straps offers an exclusive collection of 20mm straps specifically designed for sports chronographs in this category, guaranteeing precise attachments and durable materials.

What is the average lifespan of a leather strap for the Furlan Marri Chronograph Flyback 3177-A?

A quality leather strap (alligator, vegetable-tanned calf) has an average lifespan of 3-5 years with moderate use. Factors such as sun exposure, humidity, and frequency of wear influence longevity. Leather naturally develops patina over time, a characteristic highly sought by collectors. Rubber and NATO straps offer superior durability (5-8 years) due to resistance to environmental factors.
