I recently purchased a 1969 Omega Seamaster 166.042 secondhand, and I couldn’t be happier. The watch is an absolute beauty—timeless design, incredible character, and it wears perfectly on the wrist. It’s everything I hoped for and more.
What made the experience even better was the outstanding service I received. From the moment of enquiry to delivery, everything was smooth, professional, and genuinely helpful. The watch arrived exactly as described, carefully packaged, and clearly well looked after.
I absolutely love this piece—both for its craftsmanship and the history it carries. A perfect addition to my collection. Highly recommended!
