Original (authentic) Hamilton 16mm (inside) / 18mm (outside) Stainless Steel Watch Clasp Buckle with Spring Pin THREE PACK
Fits any watch with leather or fabric strap @ 16-mm (at the attachment point). Is an exact replacement for Hamilton "EFA" ("Engineered for Action") series.  These were similar to the Khaki line but were with titanium cases. You can see photos by google searching "Hamilton EFA". You can use this buckle with the Khaki series or with any Hamilton with the correct sized band or with any watch with that sized band. The "tang" or "tongue" is slightly wider than average, so if you intend to use this with some miscellaneous band, the holes in the band will probably be slightly smaller than the tang on this buckle. It would merely mean that your leather (or synthetic) will have its holes pushed open a slight bit. 
    
We also sell the complete bands in two sizes and a few colors (different listings). These all came off of original Hamilton EFA watches, which we purchased many years ago and they arrived from Hamilton with the wrong colored bands attached. Hamilton sent us new (correct colored) bands and told us to keep the extras. We have been selling these surplus bands for about 20 years since. Now, we are pulling them apart and are selling the buckles and the leather parts separately as well but all are brand new vintage stock.
 
You get three units of the part as shown in the photo, in small ziplocs.(For a single unit, see our item # 196009605631).

Free USPS "Ground Advantage" shipping (with delivery tracking) included for domestic delivery. Priority Mail with delivery tracking is available as an upgrade for domestic delivery for $5.00 extra.

We usually ship next day and sometimes even same day but ask for up to three business days lead time to dispatch shipment.

For international shipping: We only offer international Priority Mail with delivery tracking for $10.00. 

Money back if not delighted--within 14-days.  We will even pay for the return shipping (from USA Buyers). For international buyers, they would please pay for return postage. ***Please request an R/A from us by messaging first*** That way, we can send you a prepaid return label addressed to our return center, which is a different address from our shipping center. The return label will always be by USPS Ground Advantage with delivery tracking.  You only would need to drop the item off at your post office and get a receipt from the counter clerk. (For international returns, we would provide you with the shipping address to our returns center).

Thanks.
NOTE: When the available quantity shows one only, it usually means we only have one available but sometimes it can mean that we only have one which has passed preliminary (fast-track) quality control. Before we ship, we do a second, more extensive quality control and change the battery on every outbound watch.

Also: We do not give feedback to buyers unless they request it through messaging.  Thanks !
