Frequently asked questions

What is the lug width of the Breitling Superocean A1739102BA78134A?

The lug width of the Breitling Superocean A1739102BA78134A is 20mm. This measurement is taken with a digital calliper at the inner gap between the two lugs of the case, at the narrowest point. Respecting this dimension is essential to ensure correct strap fitment and proper spring bar alignment.

What is the best strap for the Breitling Superocean A1739102BA78134A?

The ideal strap depends on the intended use. For aquatic or outdoor environments, an FKM fluoroelastomer or vulcanised rubber strap offers the best performance. For urban or smart-casual wear, a flat-grain Porosus alligator strap with a plain finish complements the muscular 44mm case beautifully. Vegetable-tanned calf leather develops a natural patina over time. In all cases, a 20mm lug width and 18mm buckle taper are recommended.

How do I change the strap on the Breitling Superocean A1739102BA78134A?

To replace the strap on the Breitling Superocean A1739102BA78134A, use a thin-tipped spring bar tool, preferably with a stainless steel fork to avoid scratching the lugs. Insert the tip into the spring bar slot, compress the bar and slide it out laterally. Work on a soft surface to protect the case. Replace spring bars showing signs of wear at the same time.

Are there aftermarket straps compatible with the Breitling Superocean A1739102BA78134A?

Yes, the Breitling Superocean A1739102BA78134A features straight standard 20mm lugs, compatible with a broad range of quality aftermarket straps. Milano Straps offers bespoke handcrafted straps by Casati Milano in alligator, calf leather, rubber, and NATO nylon, with fully customisable stitching and buckle options. Compatibility is ensured for any strap fitted with 20mm spring bars.

How long does a leather strap last on the Breitling Superocean A1739102BA78134A?

The lifespan of a leather strap depends on material quality and daily care. A high-grade alligator or calf leather strap, treated with appropriate conditioner and kept away from prolonged water and perspiration exposure, can last between three and seven years while retaining a presentable appearance. Vegetable-tanned leather develops patina with wear, gaining aesthetic value over time. Milano Straps provides an 18-month guarantee against manufacturing defects.
