ETA inside and tritium lume...makes for a good functional and reliable watch that has the lume of a sport watch, and (usually) the looks of something a bit dressier. Good sartorial/situational versatility is the result. "Well below retail" is the right price to pay for any watch that has a largely unmodified ETA movement inside. They are fine products, but they don't need to be bought at full price.

If your friend is offering you a good deal and you like the watch(s), go for it, but only after checking on the WWW to see what good quality pre-owned ones are actually selling for, particularly if the seller (Tourneau, for example) offers a warranty, something your friend cannot offer. It's one thing to do and receive favors from friends, and it's good to avail oneself of a good deal when one comes along, but doing so without some benefit over buying from more traditional sellers is pointless, especially if, aside from the friend's offer, one wasn't hankering for that watch in the first place.

(FYI, the H3 tubes will need replacing somewhere around 12 years after the watch (actually the tritium) was created as that's the half life of tritium. If they aren't replaced, you'll lose the glow in the dark feature.)

All the best.
