Escala en el Bisel de Buceo y luminova a las 12

• The presence of a time-preselecting device, for example a unidirectional rotating bezel or a digital display. Such a device shall be protected against inadvertent rotation or wrong manipulation. If it is a rotating bezel, it shall have a minute scale going up to 60 min. The markings indicating every 5 min shall be clearly indicated. The markings on the dial, if existing, shall be coordinated with those of the preselecting device and shall be clearly visible. If the preselecting device is a digital display, it shall be clearly visible.

• The following items of the watch shall be legible at a distance of 25 cm (9.8 in) in the dark:
  • time (the minute hand shall be clearly distinguishable from the hour hand);
  • set time of the time-preselecting device;
  • ndication that the watch is running (This is usually indicated by a running second hand with a luminous tip or tail.);
  • in the case of battery-powered watches, a battery end-of-life indication.

• The presence of an indication that the watch is running in total darkness. This is usually indicated by a running second hand with a luminous tip or tail.

• Magnetic resistance. This is tested by 3 expositions to a direct current magnetic field of 4 800 A/m. The watch must keep its accuracy to ± 30 seconds/day as measured before the test despite the magnetic field.

• Shock resistance. This is tested by two shocks (one on the 9 o'clock side, and one to the crystal and perpendicular to the face). The shock is usually delivered by a hard plastic hammer mounted as a pendulum, so as to deliver a measured amount of energy, specifically, a 3 kg hammer with an impact velocity of 4.43 m/s. The change in rate allowed is ± 60 seconds/day.

• Resistance to salty water. The watches under test shall be put in a 30 g/l NaCl (sodium chloride) solution and kept there for 24 hours at 18 °C to 25 °C. This test water solution has salinity comparable to normal seawater. After this test, the case and accessories shall be examined for any possible changes. Moving parts, particularly the rotating bezel, shall be checked for correct functioning.

• Resistance of attachments to an external force (strap/band solidity). This is tested by applying a force of 200 N (45 lbf) to each springbar (or attaching point) in opposite directions with no damage to the watch of attachment point. The bracelet of the watch being tested shall be closed.

• Marking. Watches conforming to ISO 6425 are marked with the word DIVER’S WATCH L M or DIVER'S L M to distinguish diving watches from look a like watches that are not suitable for actual scuba diving. The letter L indicates the diving depth, in metres, guaranteed by the manufacturer.

asi es compañero, ya he leído eso, lo que no me queda claro es si el punto de la luminova es indispensable o con solo estar indicado con el triangulito a las 12 es mas que suficiente-

Más allá de todo, el triangulito es mucho más útil que el número 60 para indicar el tiempo de inmersión. Igual ahora eso ya es prehistórico.

Perdón por la ignorancia pero por qué es del siglo pasado? porque ahora se usan computadoras de buceo? o porque lógicamente llevan linterna para sumergirse y no es muy funcional la luminova?

Porque actualmente se utilizan ordenadores para controlar todo lo referido a la inmersión. El reloj diver pasó a ser algo romántico en el buceo con botella. Ojo que yo no bajo sin algunos de mis queridos divers... Y tampoco sin el ordenador
