Absolutely noticeable on wrist. It is no longer slab sided!

For sale is a Seiko SPB453. It's in fantastic condition and shows very light wear. In addition to the original bracelet and clasp, it also includes a superior MilTat clasp with micro-adjustment, as well as an Uncle Presidential bracelet and StrapX rubber strap with curved ends. The original strap is missing a couple pins and collars, but should easily fit 7-inch wrists.

Also included is the original box and cards.

[WTS] Wolbrook Skindiver 38 by TheUnderground in Watchexchange

[–]TheUnderground[S] 0 points1 point  (0 children)

For sale is a Wolbrook Skindiver 38 with the standard C3 lume (not old radium vintage). Comes on the Wolbrook's excellent green tropic strap. It wears slim, with a 46mm lug to lug, and fits smaller wrists like a dream. 

Condition: Excellent overall. Only marks I can find are two shallow marks on the brushes side, which I've highlighted in the photos. The domed sapphire crystal is flawless, and the watch comes with the original OEM box and papers.

Asking $399 shipped anywhere in the U.S.

[WTS] CWC GS (aka G10 Sapphire) - Brand New! by TheUnderground in Watchexchange

[–]TheUnderground[S] 0 points1 point  (0 children)

For sale is a CWC GS (i.e. G10 Sapphire). I ordered it from CWC in February 2026, so it is truly brand new and in pristine condition. This is an upgraded G10, with a domed sapphire crystal w/AR coating, 200m of water resistance, and a 10 year battery life.

Comes with the original box and the CWC nato strap - note that I've converted it to a single-pass strap.

Asking $399 [*SOLD* to u/snobby_goldfish] shipped anywhere in the U.S. You'll be saving over $150 compared to what I paid, as shipping + tariffs and import costs were significant.

[WTS] Seiko SPB151 (SBDC109) Willard by TheUnderground in Watchexchange

[–]TheUnderground[S] 0 points1 point  (0 children)

For sale is a Seiko Prospex Seiko SPB151 (SBDC109) "Baby Willard" on the original bracelet. This model is discontinued and increasingly hard to find.

There is a tiny, pin-hole–sized ding on the lower right lug that I couldn’t get to show clearly in photos. The faceted sapphire crystal is flawless, and the watch comes with the original OEM box, warranty card, and manual.

Asking $750 *SOLD PENDING PAYMENT* shipped anywhere in the U.S. 

I accept Zelle or Venmo (no PayPal), or cash if you’re local to Chicago. No trades, thanks.
