Time is infamously relative. ⏳ Whether an activity takes seconds or hours depends on your point of view. For astronauts living off-planet and experiencing roughly 16 sunrises and sunsets a day, the concept of time is even more warped. If astronauts float through space, do they also cruise through an altered sense of time? Go to our @instagram Story to find the answer. • 👨‍🎨 @inkbyalex

This Schatz Royal Mariner ship clock is ready to go back to it’s owner. This clock is special cause it ‘beats the glass’ The expression goes back to the old days when time on board of a ship was measured through the use of a sand dial. By turning it, the sand runs from one glass into the other. One load of sand takes 1/48th of a day or 30 minutes. Each time the glass was turned, the gong was beaten to inform the crew. This clock beats the glass in a cyclis of four hours, the time of a watch on board of a vessel. • • • • • • • • • #clock #shatz #marine #fisherman #vessel #revision #alarm #watch #boat #glasses #sanddial #onlinewatchrepair #navyseals #navy⚓ at Belgium
