Watch movements were manufactured in silver or a gold tone. Please select your preference. All cuff links are set in sterling silver with swivel findings. While all movements originally had crowns (winders) many detached thru the decades. Tokens doesn't amend or alter the movement. If there is no longer a winder we simply set as is for a streamlined look. Please select your preference. Note watch parts are not functional and do not wind. Watch brands will vary. Each pair of cuff links comes gift-boxed with a Certificate of Authenticity.
