Strap for Top Time B01 Gino Bartali

The Breitling Top Time AB01767A1C1X1 has a lug width of 20mm. This measurement can be verified using a digital calliper, measured at the narrowest internal point between the lugs where they meet the case. The buckle end width is typically 18mm.

For the Top Time, a vegetable-tanned calf leather strap in a matte finish is the most coherent choice with the instrument-dial aesthetic: it develops a genuine patina over time and echoes the spirit of 1960s chronographs. For formal settings, a large-grain alligator strap works well; for sporting use, a nylon NATO is both practical and period-correct.

The strap is replaced using a fine-tipped springbar tool inserted into the lateral hole of each lug to compress the spring bars. It is advisable to work on a soft surface to avoid scratching the satin-finished case. Original Breitling spring bars have a 1.8mm diameter; replacing them with reinforced bars is recommended when fitting heavier leather straps.

Yes. Any strap with a 20mm lug end is technically compatible. Milanostraps.it offers a curated selection of handcrafted straps in various materials, all with a 20mm attachment and typically an 18mm buckle end, available bespoke or ready to ship.

A quality leather strap worn daily typically lasts between 18 and 36 months. The key factor is exposure to perspiration and moisture. Rotating between two straps and applying a leather conditioner every three to four months will significantly extend its lifespan. Vegetable-tanned leathers, in particular, develop a desirable patina that adds aesthetic character over time.
