    Hi everyone :) I just picked up a SBBN033, and would like to install a ceramic bezel as well as replace the crystal with one that's sapphire... Can anyone offer recommendations on where to source a sapphire crystal and ceramic bezel insert? Also someone that would be recommended to install...

    I recently bought a Seiko Tuna SBBN031, I really like the watch and how it looks but the crown hits me in the hand even though it's at the 4 o'clock position. So, I was wondering is it possible to rotate the dial on the 7C46 movement 180 degrees so that the crown would be at the 10 o'clock...

    Up for sale today is my Seiko "Tuna" SBBN031. The watch is in excellent shape with no distinguishable marks on the shroud, bezel or dome hardlex crystal. There are some desk diving marks and scratches on the stainless steel bracelet and titanium Marinemaster clasp, but nothing serious. I bought...

    Chapter ring: slightly misaligned. (OK, it's a Seiko diver. I would be more surprised if it was aligned.) Handset: misaligned by about five minutes. (To avoid gritting teeth, don't look at the watch at 3:00, 6:00, 9:00, or 12:00.) Day and date wheels: different shades of black. Day and date...

    Hi! I'm selling my beadblasted GMW-B5000, a really cool piece that stands out among the other shiny B5000s. The watch has been professionally beadblasted with sand and then beadblasted with glass beads to get a smooth and light finish. I have done four beadblasted GMW-B5000s in total, one of...

    I've got some watches—including some expensive ones, for me—with typical so-so lume. Then I put on my Seiko SBBN031 300m Tuna, go outside for a minute in what seems to be twilight, come back inside, and it's like my wrist is on fire. What does Seiko know that everyone else doesn't? Is this...

    SOLD I am the original owner. Purchased from Chino in January 2017. I thought this was a "forever" piece, but have decided to get shrink my collection. Comes on a Maratac Mil-Series strap. Includes box, warranty card, etc. Crazy accurate. Check out the photo of my latest 115-day Watch Tracker...

    SOLD - Thank you WUS and buyer! =] I have for sale a new SBBN031 Seiko OEM bracelet that would work well with any of the stainless/silver tunas. It has a brushed finish with narrow polished inlays. The sides are polished. It's visually like a MM300 bracelet that was spec'd for the tuna. 22mm...

    Love these watches and will be buying one shortly. Don't care about the price differential-whichever one I pick up will go on a NATO. Two concerns: I have a 6.75" wrist and am a bit worried about size. The black 035 should look smaller-black cars look smaller than white cars-but is that...

    Bought this on a whim, would like to keep it, but have to unload some watches. This is brand new in box, never removed the plastic, never sized the bracelet, never removed any tags. It is quite a stunner. The new hands really grew on me and I now prefer this more modern interpretation of the...
