AnchorFLEX™ Flagship End-Link Strap

Integrated look. Everyday simplicity.

Designed to pair seamlessly with the Tudor Black Bay 58 GMT using the OEM end-links (Rivet style bracelet only) & spring bars. 

Built for End-Link Compatibility

This is the AnchorFLEX™ Flagship you know—refined for an integrated fit.

Engineered to work with the OEM end-links from your Tudor Black Bay 58 GMT, this strap delivers a seamless, case-hugging profile while maintaining the simplicity of a traditional buckle setup.

No clasp system. No complexity. Just a clean, locked-in look.

AnchorFLEX™ FKM Performance

Built from our signature AnchorFLEX™ FKM fluoroelastomer, this strap is made for real-world wear:

  • Resistant to UV, heat, and chemicals
  • Won’t crack, fade, or degrade over time so you can feel confident that your watch will stay attached to your wrist
  • Soft, flexible feel with a structured, premium finish
  • Designed to hold its shape—no cheap rubber collapse

This is performance material, elevated.

Flagship Design

The Flagship design is all about balance:

  • Clean, modern profile with subtle taper
  • Structured enough for daily wear, refined enough to dress up
  • Designed to complement tool watches—not overpower them

It’s the strap you leave on.

Details That Matter

  • Material: AnchorFLEX™ FKM Rubber
  • Hardware: 316L Stainless Steel Buckle
  • Attachment: Original OEM spring bars & End Links (Also compatible with out Premium 1.8mm Spring Bars)
  • Profile: Slim, flexible, all-day comfort
  • Length: 80/120mm. 

*Not compatible with 5-link bracelet end-links*

without committing to the full clasp system.
