Frequently asked questions

What is the lug width of the Ball Watch Engineer II DG2022A-SAJ-WH?

The lug width of the Ball Watch Engineer II DG2022A-SAJ-WH is 20 mm. This measurement is taken between the two pins of the integrated lug attachment on the case and is critical to ensure the correct fit of a replacement strap. Always verify this specification before purchasing a new strap, and refer to Ball Watch's technical documentation to avoid measurement errors.

Which strap is recommended for the Ball Watch Engineer II DG2022A-SAJ-WH?

Several options are recommended for the DG2022A-SAJ-WH: an alligator in chocolate brown for formal settings, a vegetable-tanned calf leather in cognac tones for sophisticated elegance, a textile NATO in dark grey or black to emphasise the technical character, or a black FKM rubber for aquatic environments and intensive use. The choice depends on the context of use and personal aesthetic preferences.

How do I change the strap on the Ball Watch Engineer II?

To change the strap on the DG2022A-SAJ-WH, you need a spring bar tool to extract the pins securing the strap to the case. Position the watch on a stable surface, align the spring bar tool with the pin hole and gently press until the pin is extracted. Repeat for both pins, then align the new strap correctly and reinsert the pins in reverse sequence.

Is an aftermarket strap compatible with the Ball Watch Engineer II DG2022A-SAJ-WH?

Yes, any aftermarket strap with a 20 mm lug width is fully compatible with the DG2022A-SAJ-WH. However, it is essential to verify that the strap has been designed for watches of similar diameter (47.60 mm): this ensures correct aesthetic proportions and harmonious draping. Milano Straps offers a carefully curated selection of 20 mm straps compatible with this model.

How long does a leather strap last on the Ball Watch Engineer II?

The durability of a leather strap for the DG2022A-SAJ-WH depends on the quality of the material, usage and maintenance. A high-quality alligator or vegetable-tanned calf leather ensures 4-6 years of daily wear, developing a patina that enhances its aesthetics over time. Regular maintenance (cleaning with a soft cloth, protection from excessive moisture and heat sources) significantly extends the strap's longevity.
