Uncle's notes

For a while now my zealous nephews have been bugging me to provide a milled clasp that would be compatible with their beloved 1450 president bracelet. "Challenge accepted," I said to myself with a proud smirk.

However, when it came time for the execution of the product, there was a glaring oversight by your dear Uncle (I did just turn 50, you know). My first iteration for the 1450 had a different link configuration, meaning the pin was placed in a different spot and the links connected in a different way. The first run had the pins toward the clasp, every subsequent release has them away from it. Not realizing this, I made the clasp according to the first configuration, but the majority of those sold have the more recent configuration.  All this to say, when I finished the clasp it was not compatible with the majority of the 1450 bracelets I released! Gasp!

My solution to this quandary is to provide an h-link that will connect the milled clasp to the 2nd/3rd iterations of the 1450 bracelets. For some of you, this fix will not fly. Your attention to detail is extreme, and you are generally an unhappy person living in an imperfect world (teasing). For others, you are more utilitarian in your thinking and you couldn't care less, as long as it is functional. Life is too short to give a rip about such details (my people!).

So, I offer this workaround to my nephews with the hopes that some of you won't mind what I had to do to get there, and just be thrilled that you have a milled clasp to go along with your 1450. In the pictures below you can see the two different configurations. The top bracelet is the first run and does not need the additional link. 

What's included:

One milled clasp and one h-link with two pins. 


  • Size: 32mm long by 18mm wide, connects to the 16mm tapered end. 
  • Weight: 16 grams
  • Material: 316L Stainless steel
  • Finish: All brushed with polished lateral sides and two small links
  • Adjustment: 4 micro-adjustment holes to insure proper fitment

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.
