Wearing and Maintaining Mechanical Watches

Oris Divers Sixty-Five 40mm

Setting your watch

  1. Don’t wind or set the time on your wrist, as it may put lateral strain on the stem.  Take the watch off your wrist, then set the time.
  2. Don’t overwind.  Consult your manual for the optimal number of turns (modern Seiko watches recommend 20 full rotations).
  3. Don’t set the date between 9pm and 2am, as you may break the date-change mechanism.  When setting the date, change the time first to somewhere outside of this range. 
  4. Don’t set the time backwards.
  5. Avoid watch winders, as they continuously strain the watch’s winding mechanism. Let the watch stop when you're not wearing it, and set the time when you're wearing it. That said, it's probably a good idea to have a quartz watch handy, for when you need to grab-and-go. 

What to Avoid: Water and the Elements

  1. Avoid water if your watch is not water-resistant.  Pay attention to specific instructions by your manufacturer about how much water pressure your watch handle, even if your watch is water-resistant.  If you wear a watch in the pool, while the water may not harm your watch, chlorine can still be damaging.
  2. DO NOT pull on the crown of the watch while underwater, even if your watch is a diver watch or water-resistant. This will cause water to flood the inside of your watch. 
  3. Avoid showering with your watch. Shampoo and soap can be harmful for the gears. 
  4. Seals to resist water can also crack over time, so just be careful and remember to schedule your regular maintenance, including pressure tests and (if necessary) gasket replacements.
  5. Mechanical parts may shift with shocks and hard impact. Don’t split wood, work power tools, play physical impact sports, while wearing mechanical watches.
  6. Don’t place your mechanical watch in close proximity to strong magnets like those found in speakers, TV, or your iPad. Most modern watches are magnetic resistance, but still be wary of strong magnets
  7. DO NOT start the chronograph underwater. Timing underwater should be done with a uni-directional bezel rather than the chronograph pushers. Pressing the pushers underwater can compromise the seal, allowing water into the movement, causing rust that can damage the dial or internal gears.

Maintenance

Like any car, mechanical watches need regular cleanings and oil changes to continue running effectively.  Maintenance costs vary depending on brand and complications, but most watchmakers recommend regular maintenance every 5-7 years.


Cross-threading the Crown

  • A very common way to damage the crown, other than pulling it at the wrong angle, is when you are threading it back in. Not all watches have a screw down crown but if yours does, be cautious when closing it. The crown can become jammed and cause permanent damage.  Modern Rolex watches have intricate stems specifically designed to avoid cross-threading.
  • A crown that is slightly out of alignment can allow water to get into the movement and dial, causing further damage. To avoid cross-threading and jamming the crown, take your time while screwing it back in, avoiding force. Crowns typically rotate 1.5 full turns and could be up to three. Be careful of screwing the crown too tightly, it could also become impossible to unscrew! 
  • I usually turn the crown backward first to make sure it will enter the thread smoothly when I push and turn clockwise to screw it down. If in the middle of screwing down there's a resistance, that means the thread was not entered into the thread smoothly from the beginning. Move backward again to release the crown and start it all over again from the beginning, otherwise the thread will be stripped.
  • If the crown doesn't screw in all the way and doesn't lock and seal properly, the crown is cross-threaded and need replacement. Water resistance is also affected so don't take it in water.

Mass Shooting

Liberals: we need gun control
Conservatives: it's because of terrorism and immigration
Trump: Thank you, I'm awesome

Foreign Policy

I spent an hour going through Trump's NYT interview on foreign policy.

My takeaways:
1. America is like the poorest country in the world but it should totally built up the military so the rest of the world can rent America's protection. Presumably at $12/hour.
2. Iran is a disaster but they are rich and they should totally buy Boeings.
3. China and Mexico are also super rich.  Xi Jinping totally disrespects Obama, but Trump likes Chinese people because they buy Trump's apartments or something.
4. His uncle from MIT said America stinks at nuclear and cyber warfare.

Democracy!

People in Iran cast their votes in record numbers last month because they believe the leaders they choose will shape the country's future.

People in America vote for Trump because "he tells it like it is" and "he was great with the Apprentice".

"Shi'as are not Muslims"

I've heard people mention this many times, even among relative moderates here in Indonesia.  Sometimes it's not about Shi'a, sometimes it's Salafis, Sufis, Wahabis, or others I may never even heard of.  Well my degree is in IT but I've been to a Shi'a prayer once so I'm an authority on this topic (/end sarcasm).  There are differences in practices and traditions between Shi'a and mainstream Sunni, even the shahada (declaration of faith), the first pillar of Islam, is slightly different between the two.

Regardless of the ideological differences, we need to really think about how sectarianism has been the strongest driving force behind the chaos in the Arab world.  When somebody proclaims religious legitimacy, 'my Islam is more Islamic than yours', it creates animosity, and inevitably fuels conflicts.  Islam teaches its adherents to study everything on Earth and in the heavens, and it's up to individual decisions to choose what he/she believes in, but I've never seen scripture giving you, any student of Islam, the right to declare other Muslims as heathens or apostates.

If you're feeling nostalgic, remember how Islam reached its golden age by embracing rich cultural heterogeneity and pursuit of scientific endeavors.  Ibn Sina, the father of modern medicine, al-Khawarizmi, who wrote the foundations of algebra -- they may not be household names but they really should be.  At least they should be household names for Muslim families from Nigeria to Indonesia

What the (Muslim) world needs is more unity in diversity, nation building, and economic, social and scientific pursuits -- and less bickering over tribalism and minor differences in the way we look, speak, and pray.

On Sectarianism



If you ever wonder about how the heck the Muslim world gets divided by sectarian lines, Israel vs Palestine, Shia vs Sunni, Kurdish vs everyone else, check out a recent op-ed by former Alaska governor Sarah Palin on President Obama's foreign policy.

"...The whole world weeps waiting for American leadership in these troubled times as Islamic savages commit genocide against the Christians of the Middle East and terrorize innocent people in cities across the globe..."

There are obvious errors and misperceptions: ISIS has primarily killed Shi'as, Yazidis, Kurds, Sunnis that don't pledge allegiance to ISIS, their own people, and so on; they're not committing genocide against Christians because, well, Christians had mostly fled and there's not that many of them left in the battleground.   However the implication of her (somewhat bizarre) rant is clear.  She has tranformed a civil war pitting local tribes and factions within Iraq and Syria, into a total war between Muslim and Christian civilizations.  The entire world is forced to choose sides. That's how sectarianism becomes the defining factor for the world we live in.

We are better than that. Don't fall for this nonsense.
