This watch is a quartz watch that has full stainless steel construction and a sapphire crystal. Watch runs great and is really a beautiful watch on wrist as the case shape really hugs your wrist. The dial is champagne and gives the watch a vintage vibe, I don’t have a case or extra links for this one. My wrist is 7 and 1/4, (average wrist size is 7 inches) it fits me perfectly. If you have a bigger wrist than that it’s a no go for you. Let me know if you have any questions.
