Longines – On The Fly Extension Link Installation Guide

Tools Required

• Pin-pusher tool
• Small ball-peen or nylon hammer
• Bracelet holder or block (to keep the bracelet stable)

Installation Steps

1. Remove the clasp from the bracelet

   
   
   • Use a pin-pusher and hammer to drive out the spring bar that connects the clasp to the bracelet.

   • Detach the clasp completely.

     
     

2. Remove the original connector link

   
   
   • Longines bracelets typically use friction (cotter) pins.
   • Look for small arrows on the underside of the link showing the direction to push the pin.
   • Place the bracelet in the holder with the arrow (or split end) pointing downward.

   • Using the pin-pusher and hammer, gently drive the pin out and remove the connector link.

     
     

3. Install the Steel Reef On The Fly Extension Link

   
   
   • Position the extension link where the connector link was removed.
   • Insert the Steel Reef-supplied friction pin, starting with the thin, straight end first so the wide, split end goes in last.
   • Tap gently with the hammer until the pin is flush.

   • For the final taps, place the pin-pusher between the pin and hammer to avoid marking the bracelet.

     
     

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 pin-pusher and hammer to reinstall the spring bar.

About Bracelet Fit

• You may need to adjust your bracelet attachment point along the clasp’s micro-adjustment holes to achieve your perfect fit.
