We have seen it before, nothing really special,...........
I got it for free and it was non-working with broken crystal ! Was really surprised to discover that it was using a very thick crystal and when repaired I had it inside the sea many times, swimming and spear-fishing e.t.c.....
Never had a problem for more than five years, always keeping time, always ready to go,................An almost unknown Rexstar chrono and ONLY 100m rated !
