The tides are the result of a complex intertwining of gravitational and centrifugal forces between the earth, the moon and the sun. In many coasts around the world, tides occur twice a day and occur exactly 12 hours and 24 minutes apart. The Portugieser Yacht Club Moon & Tide indicates the estimated time for the next high and low tides in a counter at "6 o'clock". This prediction is obtained by a reduction gear that transposes the regular rhythm of the hours in the constantly evolving sequence of high and low tides. The dual indication of the moon phases at «12 o'clock» has been enhanced to also show the signium and quadrature tides, and therefore also provide information on the strength of the current tides. The sigial tides, which are particularly high, occur with the full moon and the new moon. The 18-karat red gold case, the blue dial, the golden hands and the applied indexes in 18-karat gold highlight the nautical style of this timepiece. The IWC-manufactured 82835 caliber features a Pellaton refill system. Equipped with ceramic components, it boasts a 60-hour power reserve.
