  • The 4011 series of two and three display stopwatch-clocks is a unique range of large digital stopwatches with an independent time-of-day display all housed in a single case.
  • The 12 or 24-hour bright and clear time display has the option of either 57mm (2.3") high seven-segment digits for hours, minutes and seconds or 50mm (2") dot-matrix characters for hours and minutes with 30mm (1.2") characters for seconds. You have a choice of blue, green, red or yellow digits.
  • We supply an IR handset for time-setting and count-down configuration and operation. You can use the IR handset to control the first stopwatch of the 4012 and 4202 versions. The second stopwatch requires external voltage-free contacts or our 496E stopwatch control panel for operation.
  • Network operation enables multiple stopwatch secondary displays controlled by a single switch panel.

All Wharton digital clocks have many user-selected modes of operation:

  • E and NE versions can be used in stand-alone applications using their internal time references.
  • Every standard digital clock has rear connections to enable time synchronisation using one of a wide selection of time code protocols from a Wharton 5000 series master clock or suitable third party time reference.
  • You can synchronise individual clocks with a precise satellite-based atomic time reference via a control message from a Wharton 488HS series GPS or GLONASS time signal receiver.
  • N and NE versions can be controlled and synchronised to time via their 10/100Base-t Ethernet NTP connection to your existing network with accurate time information provided by a local or internet time server for simple, low-cost installation and control.

Stopwatch operation

  • Wharton 4000 series calendar clocks have time digits freely switchable between the display of time-of-day and the display of multifunction stopwatch or countdown time.
  • The stopwatch and countdown timer functions are controlled by the IR handset supplied, by an optional dedicated switch panel or by user-supplied voltage free contacts.
  • The following stopwatch and countdown timer functions are user programmable:
    • Stopwatch display modes
    • Stopwatch display resolution
    • Stopwatch count direction
    • Stop/start and hold switch actions
    • Countdown start count
    • Using external, voltage free, switch contacts - E and NE versions only
    • Network stopwatch mode - network versions only
  • Further information about stopwatch & countdown timer operation


  • The high-quality clock enclosures have a black, silver or special order finish. Case type and colour information.
  • Base model clocks are suitable for freestanding or wall mounting using the multi-angled brackets supplied. Mounting options include cases for flush wall mounting and single or double-sided clocks with mounting supports for ceiling suspension.
  • 110-230V AC, 24 or 48V DC or PoE (Power over Ethernet) power supply options.
  • All Wharton digital clock products are designed, manufactured and tested to International Quality and Performance Standards.
  • Unrivalled free product lifetime technical support with unlimited advice and information to the original user for the life of the digital clock. Many previous models are still in service more than 15 years after first supply.
