Thand want set timee crown will not screw in - Crown Watches

Unscrew crown. Some models of Sector Sport watches may have a screw down crown. Watches meant to be used in water will often have this feature. To test this try spinning the crown freely in both directions. If it does not spin freely it has a screw down crown. If your Sector has a screw-down crown, turn it in a counter clockwise motion to unscrew it until it pops free.

Pull crown out one click and set date. If the watch has a date perform this step, if not move on to the next step. Pull the crown out one click. Twist crown clockwise and counter clockwise to set the day and date to the previous days day and date. The purpose of this is to set the date by setting the time and insuring the watch is in the correct a.m. and p.m. mode.

Pull crown out to the next click and set time. Pull the crown out the to next click. This is the time setting mode. Set the time by turning the crown clockwise until the day or date changes to the current date. This is the a.m. mode. Continue to the correct time. If it is a p.m. time this will require moving one full circuit of the dial past the twelve again and then to the correct time. If you fail to do this, the date will change at noon. If there is no date, simply set it to the correct time.

Push in and screw down crown to retain water resistance. Push crown down into its furthest setting. If it is a screw-down crown, press the crown in with a finger and twist it clockwise. Be careful here not to cross thread the crown in the crown tube or it will need to be replaced. It should be smooth and easy to turn. If any pressure or resistance is felt stop and start over. If you fail to screw in a screw down crown your Sector Sport watch will not be water resistant.

HOW TO START YOUR WATCH

To start your watch remove the plastic guard from

under the crown, then press the crown in against

the case. The second hand will begin advancing in

one-second intervals.

Some deep-depth water-resistant watches require

the setting crown to be screwed in to secure

water-resistance. If your watch case has a protrusion

with screw threads, the crown must be screwed in

after setting the watch.

To screw in, push the crown firmly against the

threaded protrusion and hold in while turning the

crown clockwise. Continue to screw in the crown

until it is tight. You will need to unscrew the crown

(counter-clockwise) before pulling it out the next time
you want to set your watch

After you unscrew the crown it is already in winding position. If you pull the crown, it will go to the date setting position. Further pull of crown will set it in time setting position. Try to pull the crown till you get it in correct date setting position and change the desired date. Do not use the date setting between 10pm - 2am, as this can damage date mechanism. The best way is to pull out crown to the time setting position and set the time to 6.30(anytime) and then push the crown in to date setting position and change the date to the previous day's date. Then again pull the crown out to the time setting position and advance hands forwards (clock wise) till hands pass 12.00 (midnight) and the date changes automatically to the desired one, then adjust the time, push the crown fully in and screw the crown on.

The time setting screw is more accurately called the crown which is, in your case, a 'screw down crown'. This is done for water resistance. You must first unscrew the crown before you can pull it out. When you are finished setting the watch you must screw it back in. It may require that you press in on the crown and turn it at the same time to get the threads to catch. No need to overtighten it.

Could not find a download for instructions on this watch, but I did manage to find some basic instructions for the Sector brand. I hope this helps as this is the best I can come up with.
Good luck.

Tags have a screw down crown (winder knob) turn the knob counter clock-wise until you feel the crown unscrew (not off) then pull the crown carfully. It will pop once this is for date adjust. Then pull once more and you can now adjust the hands, set accordingly then push crown back in. After you push it back in gently compress the crown and tighten clockwise until it stops. CAUTION!!!!!!! Tags are not waterproof if the crown is not screwed back down. I hope this helps I am actually a car guy (just happen to own a couple)

To set time, you need to unscrew crown anti-clockwise direction if you have a screw-in crown watch. You need to softly and slowly pull the crown out a little bit. The best way to do this is to use first and second finger and use finger knuckle as a lever in order to pull the crown out with as little force as possible. You can feel a little "click"! Now you can set the time by turning it anti-clockwise. This would turn the minute-hour hands forward until you set the right time. When time is set, push the button back and screw the crown clockwise for a few rounds to ensure it is screwed back tight.
