Call it an homage of an homage, but you can’t deny that it’s a fine piece to put on the wrist! In line with his design philosophy to add a personal touch without taking away too much from its inspiration, @koda_watches pairs a navy blue SNXS77 dial in our NRX case and adds a yellow lightning seconds hand to give it a pop of color. The blue sunburst dial may seem too minimalist at first when compared to the waffle dial of the Powermatic 80, but it looks just right for a watch meant to be a daily beater. This build also features a day-date indicator, a step up from the muse’s date-only complication.

The recognizable shape of the NRX case and its seamless transition to the bracelet makes it an eye-catching feature all on its own, so @finemods and @mod_by_kellan both must have thought you don’t to do anything too ‘extra’ to make a beautiful watch out of it. For the face, both have decided to borrow from luxury design and added a Silver Oak-style dial, featuring a beautiful waffle design that plays nicely in the light. Silver baton hands complete the look, its slender design matching the markers on the dial and the sleekness of the case.

Fancy a custom watch build modeled after the gold Tissot PRX? @modderire had the perfect mod idea for a gilded homage, and this one really nailed the vintage vibe with its oldie-but-goodie Seiko 5 dial. If you add a few stains and scratches, you’d probably think this is legitimate piece that was made in the 70’s – the dial just matches the case so nicely that it looks OEM! Turn it around and you are greeted with a display caseback to showcase the NH movement with custom golden rotor, adding even more character to an already awesome build.

“This should be in an art gallery,” says one of the comments. You’d probably agree since the watch does look like a piece of art, thanks to the stunning art deco dial. Featuring a checkered pattern of black and gold, the dial adds an intricate look to the build using a golden NRX case as the base. You also have a black day and date wheel to match the face, while golden baton hands point to the short rectangular markers to tell the time. With that much going on at the front, @lyvmods decided to ease up on the caseback, opting for a sterile slim caseback which is the perfect choice for this particular build. Something to wear at the gala, perhaps?
