Swiss Style Compatible Apple Watch Strap Connectors Adapter - One Pair.

Includes 2 adapters and spring bars

Upgrade your Apple Watch with a precision engineered strap adapter designed to bring the look and feel of a traditional Swiss watch to your wrist. Designed with wider lugs than the Classic Adapter to create a stronger, more refined presence and a look that feels closer to a swiss traditional watch.

PVD and IP coating technology for long lasting color and durability.

Available for 22 and 24 mm Straps. 

Our Apple Watch strap adapters are CNC machined from high grade 316 stainless steel and built to extremely tight tolerances. The result is a seamless fit with no play, no gaps, and a solid connection that feels integrated with the case. These adapters create wider visible lugs, giving your Apple Watch true watch style legs similar to high end Swiss timepieces.

Adapter groups and compatibility

Apple Watch Adapter & Strap Size Guide

Apple Watches are grouped into three categories. While case sizes change, the lug width (where the adapter slides in) remains consistent within these families.

1. Small Case (Uses 41 Group Adapters)

 

If your watch is one of the smaller models, a 41mm adapter is the standard fit.

Series 7, 8, 9: 41mm

Series 10: 42mm

SE (All Generations): 40mm

Series 4, 5, 6: 40mm

Series 1, 2, 3: 38mm

Strap width supported

22mm

2. Large Case (Uses 45 Group Adapters)

For larger watch models, the 45mm adapter provides the most versatile fit across multiple generations.

Series 7, 8, 9: 45mm

Series 10: 46mm

Series 4, 5, 6, SE: 44mm

Series 1, 2, 3: 42mm

Strap width supported

24mm

3. Ultra Family (Uses 49 Group Adapters)

 

49mm adapters are specifically designed for the rugged, wider profile of the Ultra models.

Apple Watch Ultra 1 & 2: 49mm

Strap width supported

24mm

Important Warning: Check the back of your watch for the size. Do not confuse the Series 1-3 (42mm) with the Series 10 (42mm). The older 42mm belongs to the Large family (45mm adapter), while the new Series 10 42mm belongs to the Small family (41mm adapter).

 

Finishes available

We use a high quality modern plating process with advanced PVD and IP coating technology, not standard plating. This ensures deeper color, stronger adhesion, and long lasting resistance to wear, fading, and corrosion.

Each adapter is designed to transform your Apple Watch into a refined timepiece that pairs perfectly with premium leather straps. Whether you want a classic look or a bold modern finish, these adapters offer the precision, durability, and aesthetics expected from true watchmaking standards.

Note

Leather color and finish may vary slightly due to natural hide characteristics.
