Frequently Asked Questions
Why buy a Sunshine Custom Watch?
We take pride in crafting timepieces of the highest quality.
Our expert watchmakers and high-quality materials position us as a rival to luxury Swiss watch brands. Unlike competitors that rely on dropshipping from abroad, we manufacture and dispatch from our Florida watch studio.
This enables us to perform the quality control that others may overlook. We inspect all components before and after the assembly of your customized watch.
How long does it take to build the watch?
If your watch is labeled "In Stock" above, we typically ship it out in 2-3 business days. If the watch you have chosen is marked as "Back Ordered" above, it will enter a queue for our skilled watchmakers to meticulously handcraft. Please allow 2 to 3 weeks for this process.
What is the cost of shipping and how long will it take?
We offer complimentary shipping on all of our timepieces. This process typically requires 3 to 8 business days. Expedited delivery choices are available for a additional charge. Please be aware that these are estimates and are contingent on the courier.
