Good clock ordered 5 min. when measured was 4:57 min. that is very acceptable for this kind of clock.

Nice build sandwatch. Measured 15 min by stapwatch to check the watch. the bulb is made of glass

Do not understand why it was delivered to another address than the regular one.

All is good! high quality, the sand ran out 7 seconds earlier than expected.

as described. lasted praticaly 29 min and 34 s, which is excellent.
