diving bad

I'm gonna go diving in a day or two, over this weekend at tioman, who all would have known have had a mishappening over the last week, 2 singaporean divers drowned during. It was unfortunate and reminds me to be cautious of what I do, even the most professional of divers can get into an accident. Better be safe than sorry.

On the lighter note of things, I get to strap a watch and dive! And choosing the watches is a chore many watch lovers can relate.

dive ratings

From wikipedia:

The standards and features for diver's watches are regulated by the International Organization for Standardization in the ISO 6425standard. Besides water resistance standards to a minimum of 100 m depth rating ISO 6425 also provides minimum requirements for mechanical diver's watches (quartz and digital watches have slightly differing readability requirements) such as:^[16]

• The presence of a unidirectional bezel with at least at every 5 minutes elapsed minute markings and a pre-select marker to mark a specific minute marking.
• The presence of clearly distinguishable minute markings on the watch face.
• Adequate readability/visibility at 25 cm (9.8 in) in total darkness.
• 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.
• Chemical resistance. This is tested by immersion in a 30 g/l NaCl solution for 24 hours to test its rust resistance. This test water solution has a salinity comparable to normal seawater.
• Strap/band solidity. This is tested by applying a force of 200 N (45 lb_f) to each spring bar (or attaching point) in opposite directions with no damage to the watch or attachment point.
• The presence of an End Of Life (EOL) indicator on battery powered watches.

Testing diving watches for ISO 6425 compliance is voluntary and involves costs, so not every manufacturer present their watches for certification according to this standard.

this is the 'rule' for dive watches.

But online 'rates' the activities for these watches:

< 30  meters - no touching of do not get it wet, not even sweat

30 meters - sweat, light amount of handwashing/shampooing, under light drizzling rain

50 meters - heavy rain, shower

100 meters - swimming, less than 2m snorkelling

150 meters - swimming fast, shallow depths diving like 5m, dipping ur hand in the sea on a travelling speedboat

200 meters - proper dive watch but no one dives below 50m normally.

the depth goes crazy till about 3000m! like if there is such a deep ocean, if u are at that wretched depth below, will you look at the time?

People even think that movement under water will create pressures that flood watches, that is all bunch of hokum.

Been watching nothing but breaking bad for awhile now.
