Frequently asked questions

What is the lug width of the Bastian Antoni Turbulent BA01.STEEL/BROWN.8719326505893?

The Bastian Antoni Turbulent BA01.STEEL/BROWN.8719326505893 features a 22-millimetre lug width. This dimension was deliberately chosen to balance the proportions of the 45-millimetre case, ensuring visual harmony and compatibility with a wide array of artisanal straps. To verify compatibility, measure the distance between the two lateral attachment points of the case with a digital calliper.

Which strap is best suited for the Bastian Antoni Turbulent?

Selection depends on intended use and aesthetic preference. For formal occasions, an alligator leather or vegetable-tanned strap in dark brown heightens the segnatempo's constructive refinement. For a sport-casual approach, a charcoal NATO or navy rubber maintains the technical gravity of the timepiece. In vegetable-tanned calf, natural patina develops over time, creating unique personalisation linked to leather ageing.

How do I change the strap on a 22mm lug width watch?

Proceed with care: position the watch on a soft surface (mousepad or cotton cloth). Locate the transverse pins that traverse the lateral lugs—often accessible from the case back. Use a spring bar tool to compress the pin's extremities and extract it. Remove the strap and repeat on the opposite side. Installation of the new strap follows the inverse path: align the pins with the holes and insert with uniform pressure until the securing click occurs.

Is there an aftermarket strap compatible with the BA01.STEEL/BROWN.8719326505893?

Yes, any strap with a 22-millimetre lug width is compatible with the Bastian Antoni Turbulent. Milano Straps offers a curated selection of vegetable-tanned leather, alligator, NATO fabric, and rubber straps, all precisely calibrated for 22mm lugs. Always verify the width specification on the product sheet before purchase to avoid constructive incompatibility.

How long does a leather strap last on a watch like the Turbulent?

A quality vegetable-tanned leather strap, worn moderately (3-4 days weekly), resists deterioration for 3-5 years before requiring replacement. Longevity depends on ambient humidity, frequency of wear, and applied care (avoid prolonged immersion; condition once annually). Alligator leather, being denser, may last 5-7 years. Rubber offers superior durability (7-10 years) but less perceived aesthetic refinement.
