If you want to avoid the hassle and risk of selling your parts through social media and other online forums, we provide a quick, easy, and, most importantly safe solution.  

We currently buy Seiko and Seiko-compatible parts of all types and in all conditions, even damaged ones. We also purchase OEM Seiko and modded watches, as well. 

Our pricing is transparent and flexible to ensure your transactions are done securely and fairly. Contact us today to learn why we are the preferred and trusted source for Seiko part sellers. 


Because we need to make a profit on every part, our offers will come in lower than what you can receive selling directly to another modder. 


Step 1: Contact us here, through our seller’s portal and let us know what you’d like to sell. We typically respond within 24-48 hours with next steps. 

Step 2: Mail us your parts! No need for pictures or detailed descriptions. In order for us to make you a fair and compelling offer, we need to evaluate every part in person first. 

Step 3: Once we’ve received your parts, we typically take 2-3 business days to perform our inspection and determine a valuation for your parts.  

Step 4: After we’ve shared & agreed to an offer, we will pay you out via PayPal, Venmo, or Zelle. 


Fill out the contact form below with a list of the parts you're interested in selling and we will respond within 24-48 hours. Email us at info@secondhandmods.com with any questions.
