Strap for Superocean 44 Hainan

The Breitling Superocean A173677A1B1S1 has a lug width of 20mm. This is the internal distance between the case lugs where the spring bar sits, and it determines the correct strap width at the attachment point. To verify it, measure with a calliper between the two lugs at the point where the spring bar is inserted.

For the 44mm stainless steel Superocean A173677A1B1S1, the most suitable materials are vulcanised rubber for sporting and marine use, vegetable-tanned calf leather for elegant everyday wear, alligator for formal occasions, and ballistic nylon NATO for maximum tool watch functionality. The ideal choice depends on your primary use and the dial colour of the watch.

To replace the strap on the Superocean A173677A1B1S1, you will need a spring bar tool to compress and remove the spring bars from the 20mm lugs. Insert the forked tip of the tool into the lug hole or groove, compress the spring bar and slide the strap free. Take care not to scratch the stainless steel case. If you are unfamiliar with the process, we recommend visiting a watchmaker or a specialist atelier.

Yes, the Superocean A173677A1B1S1 with its 20mm lug width accepts any aftermarket strap in a standard 20mm width fitted with standard spring bars.

Lifespan varies according to material and usage. A vegetable-tanned calf leather strap worn daily, kept away from prolonged water or perspiration exposure, typically lasts 2 to 4 years, developing a distinctive personal patina over time. Alligator leather, with its denser and more compact natural fibres, can last between 4 and 7 years with proper care. For water-intensive use, rubber is the most durable option. Casati Milano provides an 18-month guarantee against manufacturing defects on all straps.
