Hydrographic Service (HS) Chronograph

  • Ivory/Off-White
  • Quartz
  • Brushed Steel
£600

In the 1940s and 1950s, the Royal Navy issued asymmetrical chronographs to its Hydrographic Service and Fleet Air Arm officers. Amongst these, Lemania-built models were favoured for their clarity and precision in the harshest conditions.
The Newmark HS Chronograph is a faithful re-issue of these naval timepieces—an authentic continuation from a name with true heritage. Then, ship captains, navigators, and aviators relied on theirs. Now, the HS returns for a new generation.

History

Where once only Royal Navy officers held these HS-issued chronographs, today the HS offers watch enthusiasts a chance to own a legit re-issue—an heir to a storied lineage. Combining midcentury design cues, rugged build, and modern accuracy, the Newmark HS Chronograph is not merely a throwback—it’s a functional vessel of history.
