Crossover Instructions

Congratulations on your purchase of the Benjamin Banneker “Crossover” watch.  The watch is powered by a mechanical movement made by the Seagull Watch Company.  A mechanical watch is the height of craftsmanship and it is this type of mechanical movement that first inspired Benjamin Banneker to begin construction of his famous clock which he completed in 1753.

It has no battery, microchip or circuitry.  Watch parts are machined to near perfection at microscopic sizes and tolerances and can produce accuracy to within 2-3 seconds per day.  Seagull is one of the largest producers of mechanical movements in the world.  The TY2721 movement is a mechanical, hand wound movement, and the mainspring retains its energy on a full wind for up to 48 hours. 

Winding Instructions: Do not pull the crown and stem out when winding. Always make sure the crown is depressed fully.  Wind the crown and stem clockwise or forward to initiate the tightening of the mainspring.  You will see the spring steel mainspring between the 11 o’clock and 1 o’clock position tightening.  You will also see the gold-color balance wheel at the 8 o’clock position begin to oscillate and the second hand at the 6 o’clock position will begin its travel.  The mainspring is tight when it fully contracts around the staff.  You will also hear the watch clicking when the mainspring is fully wound.  Approximately 20-30 clockwise or forward turns of the crown should fully tighten the mainspring.  Do not over wind the mainspring as it could damage the movement of the watch – if you feel any resistance don’t wind further.

Setting the Time: Use your thumb and index finger to pull out the crown and stem until it clicks.  Wind the crown on the winding stem clockwise or forward to position the hour and minute hands to the desired time. Push the crown and stem in so it returns to its initial position.    

Maintenance: A wound watch will run accurately from 36 to 48 hours. 

  • Mechanical watches should be wound at least weekly if possible.
  • It might become routine if you wind the watch when dressing in the morning or before bed.

Store your watch properly. Watches are delicate instruments and you should be cautious when putting one in storage. The best way to protect your watch is by wrapping it in a protective coating. This could be bubble wrap, another protective fabric, or the original packaging.

  • You should store the watch in an environment that is cool, clean, and dust free. Keep the watch out of direct sunlight. 
  • You should attempt to wind it every week while in storage.

DO NOT attempt to repair the watch yourself.  Take it to a watch repair professional or contact us at [email protected]
