| [#5] 坐井觀錶 ISO 6425 divers' watches standard The standards and features for diving watches are regulated by the ISO 6425 - Divers' watches international standard. ISO 6425 defines such watches as: A watch designed to withstand diving in water at depths of at least 100 m and processing a system to control the time. Diving watches are tested in static or still water under 125% of the rated (water)pressure, thus a watch with a 200 meter rating will be water resistant if it is stationary and under 250 meters of static water. The testing of the water resistance is fundamentally different from non-dive watches, because every watch has to be fully tested. Besides water resistance standards to a minimum of 100 meter (330 ft) depth rating ISO 6425 also provides minimum requirements for mechanical diver's watches (quartz and digital watches have slightly differing readability requirements) such as: • 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 (9.84 in) in the dark: o time (the minute hand shall be clearly distinguishable from the hour hand); o set time of the time-preselecting device; o indication that the watch is running (This is usually indicated by a running second hand with a luminous tip or tail.); o 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 www.avionica-watches.com • 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 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. |

| [#7] 坐井觀錶 newnew兄，有想過，亦 draft 咗幾張錶殼 drawings，想話做一個 series 的基準底座配帶，上面套不同款錶頭，不過問過啲廠，MOQ 數量唔細，國內細廠質量/精度未達要求，番鬼佬報價又太貴，自己又咁上下年紀，作罷了。 |
