Reference guide
Watch references by power reserve
How long each reference runs off the wrist, as its maker states it. The seventy-hour line is where a watch survives a weekend in a drawer and stops being something the owner has to reset on Monday.
81 of 96 references carry this figure. The other 15 are absent because their makers do not publish it — not because it is unknown to us.

Stops if it is put down for two days.
