Specializing in Omega, this shop has an expansive selection of classic dive watches in addition to very rare pieces like a rose gold Omega Speedmaster, and a pristine Omega Seamaster 300 “Big Blue,” the first chronograph able to be used underwater. They also are one of the very few places to stock brand new Zeno-Watch Basel models. The store policy is that only watches graded above 80% condition are allowed to be shown, so you can be assured that only the finest specimens are found here.

Khun Wichai used to pen the monthly Retrograde column in Watch World Wide magazine. So he knows his stuff, and is always willing to have a chat about the latest trends. Check out this stall for NOS (new-old stock)and secondhand pieces. His strap making work is rather impressive as well, so be sure to check out his handcrafted stingray and leather straps.

Not only does this shop have a great selection of secondhand watches, but it also deals in just about everything from sunglasses to model planes. The watch selection isn’t chock full of rare, expensive timepieces but rather an assortment of robust and reliable well-known marks. You’re bound to consistently find some old automatic Seiko’s and quartz Tag Heuer’s from the seventies through nineties.
- Seiko 6309 1980s, B12,000
