The ISA caliber 9003/7301 is an ani-digi quartz movement. It is found in entry level luxury watch brands such as Renato and even the National Geographic watch. As a world timer, the 9003/7301 has 24 programmed time zones and the ability to automatically set the analog hands based on selecting a time zone. ISA calls this the Voyager Function. The LCD screen screen can be set to positive or negative, meaning it can be light or dark for visibility preference.
Some of the topics covered in this caliber listing:
ISA lists this caliber as “Swiss Made” yet also refers to it as “Far East Assembly”.
The ISA cal. 9003/7301 takes a large CR 2016 battery cell. It has a low battery indicator (aka EOL). With a new battery installed, your watch should run for about 58 months if you do not use any of the extra functionality. The more you use the functions, the less time you will get out of the battery. For example, daily use of the alarm and backlight may only get about 42 months of battery.
Restarting After Battery Change:
After battery insertion, or if movement does not work correctly after battery setting, a reboot can be carried out by connecting the pad 1 with the pad 2 as we can see on picture below. Hold this position for 3 seconds to ensure the reset. This operation is far better than removing and reinserting the battery and thus ensures a correct restart of the movement.
After that, the movement is in the same configuration as after a battery change and an initialization procedure has to be carried out as described in user manual.
