Jubilee 'On The Fly' Extension Link

Tools Required

• Oyster bracelet: 1.6 mm flat-blade watchmaker’s screwdriver
• Jubilee bracelet: 1.4 mm flat-blade watchmaker’s screwdriver
• Push-pin or spring-bar tool
• (Optional) Purple Loctite 222 low-strength threadlocker

Installation Steps

1. Remove the clasp from the bracelet

• Use a push-pin or spring-bar tool to depress the spring bar that connects the clasp to the bracelet.
• Detach the clasp completely.

2. Remove the original connector link

• The connector link is the last link on the bracelet, attaching directly to the clasp.
• Use the correct screwdriver to remove the screw securing it to the bracelet.
• If you have a Submariner or Sea-Dweller: the OTF extension link replaces the diver’s extension on your clasp. The diver’s extension provides ~1 inch of extra length for wetsuits and is not designed for daily micro-adjustment.

3. Install the Steel Reef On The Fly Extension Link

• Position the extension link where the connector link (or diver’s extension) was removed.
• Use the provided screw to attach it to the bracelet.
• (Optional) Apply a very small drop of Loctite 222 to the screw threads before tightening.

4. Reattach the clasp

• With the extension link in the open position, slide the clasp’s connector into the extension link’s folding arms.
• Use the spring-bar tool to depress the spring bar and secure the clasp back onto the bracelet.

About Bracelet Fit

• The Steel Reef OTF link adds 5 mm of instant, on-the-go adjustment — the equivalent of a half-link.
• The original Rolex connector link is typically ~10 mm long. Our OTF link is 5 mm when closed and 10 mm when open.

This means:

• If left open, your bracelet will be the same length as before installation.
• If left closed, your bracelet will be 5 mm shorter.

To keep your original “base” fit with the OTF closed (and still have +5 mm available when opened):

• Move the bracelet attachment point along the clasp’s micro-adjustment holes to lengthen it.
• If you are already on the last micro-adjustment hole and cannot lengthen further, add an extra link (many full-set watches include a spare link).
• Steel Reef also sells half-links and full-links for all Rolex models on our website.

Submariner & Sea-Dweller owners: Since the OTF replaces the diver’s extension, you will need to experiment with micro-adjustment settings and/or links to return to your preferred base fit.

We don’t make “universal” links. Every Steel Reef component is individually designed for a specific Rolex reference and cut from the same grade of steel your watch is made from. Machined to ±0.02 mm, our links match OEM-inspired tolerances and finish so precisely that they disappear into your bracelet — the only difference is the improved comfort and balance. This level of precision takes time, expertise, and cost to achieve, which is exactly why serious collectors choose Steel Reef.
