Uncle's notes

While I love wearing my Speedmaster, there was something about the bracelet that just wasn't right with me. For some reason between the removable links and micro-adjustments I was still unable to achieve the perfect fit. Add to that I am a vintage guy at heart and the stock bracelet just looks too modern to me. So, I decided to take the plunge and make remake some of the classic models for a new generation of Omega lovers. 

Please note - we cannot guarantee compatibility with special edition Speedmaster's.

What's included

One bracelet, one pair of end-links, one pair of 1.8mm spring bars


  • Lug width to Buckle: 20mm to 16mm (19mm to 16mm)
  • Length: Long- 175mm
  • Min.length after adjusted : 115mm
  • Buckle : Stamped 316L Stainless Steel 16mm Pressure Clasp 
  • Thickness: 3.1 mm
  • Net Weight: 56 grams
  • Finish: Brushed
  • Spring bar diameter: 1.8mm 
  • Lug end style : Standard (Hollow) Curved End 
  • Adjustment type : Pins
  • Material : 316L Stainless Steel, all solid links (standard end links) 

Installation tips

Mounting these can be a challenge because the opening is somewhat narrow. I have found it is easier to flip the watch over and mount from the underside. Make sure you have the proper spring-bar tool to help guide those bars into place!

A couple of guys mentioned that they love the vintage pressure clasp, but wish it had a bit more "snap" when securing it. You can adjust the tension by slightly moving the small tab on the inside of the clasp. Moving it toward the hinge (away from the bracelet) very slightly will make it harder to close and create the desired effect. Again, a tiny adjustment with needle-nose pliers and check, repeating if needed. (See last picture).


Designed to fit: 19mm (FOIS) and 20mm Speedmaster, also some Seamaster models

      Processing, Tracking & Insurance

      Please allow 1-2 days for processing time.  All of our shipping options include tracking and insurance. First Class International may have limited tracking options depending on destination. 

      PLEASE NOTE: If you are an international customer and you chose USPS as the carrier, it is common for the package to sit for 2-3 weeks at a distribution center in Los Angeles. Nothing is wrong and it is not lost. This is where they wait for flights. If you prefer something faster, please select Fedex, which is 3-5 days to your door.


      As of July 1, 2021, all orders shipped to the EU will require a value added tax (VAT) to be paid by the recipient at time of delivery.  Other international orders may require a customs duty once reaching their destination. These fees are a separate charge often imposed by the destination country or region and are not the responsibility of Uncle Seiko.

      PLEASE NOTE:  I am aware that many countries charge a large import fee on top of the purchase price. This money is collected at the time of delivery and has nothing to do with Uncle Seiko Straps. Because the fees are based on the price of the item, it is advantageous for buyers to request a lower price recorded on the customs form. However, I cannot alter the price. In the U.S. it is considered a crime (mail fraud). Thank you for understanding. 

      German Customers

      When USPS packages arrive at the customs office in your country, they are marked as delivered. What typically happens is that within the next few days, they contact you to pay import fees to receive the package. If you have not received your package and it shows as delivered, do not be alarmed, as they should be contacting you soon.
