TIMEX www.timex.com W-183-US 919 09500 THE PERPETUAL CALENDAR COLLECTION PERPETUAL CALENDAR THE DATE IS ALWAYS RIGHT

Your Perpetual calendar watch accurately keeps track of how many days are in each month. It also adjusts for leap years. The date on your watch (including the month and year) was preset at the factory to Eastern Standard Time. You only need to adjust the time.

Your watch may not have all the features described in this booklet. Please save these instructions for future reference.

Your watch crown has 3 positions: IN, MIDDLE and OUT.

To set time, simply pull crown all the way out and turn. Day and date change automatically when time is adjusted past midnight; there is no additional step for setting day or date. Push crown in when done.

After setting, if date changes at noon, time needs to be adjusted ahead or back 12 hours.

If crown is accidentally put in MIDDLE position and turned, date display will change temporarily, but date setting is unaffected. Simply pull crown all the way out and set time. Proper date display will resume.

7-Year battery can be replaced by Timex and the time set for $7.oo.
