LED HSD 601 10-0275-00
The shop did not have the right manual - yours will show HSD 601 and a different picture
but the setting of the watch is trivial. Press either the upper button (time adjustment) and the recessed adjust button on the left of the case at the same time, and the digits start blinking in order to be set. My watch is the Series 10-0275-00 and I think both these LED re-issues feature a similar or the same caliber. The difference is that this watch in the picture has two displays, the top display for the date and the bottom display showing 10:38 PM for the time.
