close up of my Blue Mako

Man.... regretting not getting it last month when it was on massdrop. Everything speaks to me about this watch... the hands, raised markers, number font....

Next time should ask K2 if they have this model in stock.

Thanks for the info! Then I will have to fall back on my backup soruces: Skywatches and Amazon haha.

But no hurry, my watch budget is already tied up for the next few month: Feb is Ventus Black Kite, March is Mod for my Seiko SRP, and April maybe Seiko FFF.

Basket... My Panerai straps average 100 euros each... But not very smelly because I rotate a lot.

i will say maybe 3 to 4 months cos i sweat alot... all my leather straps is low $10 so no issues if i keep changing to new one....

Can also check out lazada plus their coupon code. May be able to get good deal too.

Random thought during work.

Does self-winding watches work in Space? Let's suppose in zero-gravity.
Does the rotor moves?
*don't talk about the manual winding function in an self-winding watch.

Omega speedy is manual winding, so it should work.
but gravity may cause the balance wheel to stop working?

haha discuss.

but........... copy from some other forums.

"I've thought about this a bit myself and looked into it a bit and concluded that an automatic watch WILL IN FACT work in space, even in the presence of zero gravity.

In reading about the manual wind Omega Speedmaster, it appears to me that NASA chose the manual-wind Omega Speedy for use in space based on very specific criteria which included a long list of POSSIBLE severe environments (and I think the Speedmaster was chosen in 1965 and Omega didn't make an automatic version until 1973...for whatever reason, Omega submitted the manual wind version to Nasa for the 1978 selection and it was selected based on the long list of criteria).

Nasa mistakenly believed that gravity was required to spin the rotor of an automatic watch, however, which was an incorrect assumption. In reality, INERTIA moves the rotor of an automatic, not gravity (The principle of inertia can be stated as - "In an isolated system, a body at rest will remain at rest and a body moving with constant velocity will continue to do so, unless disturbed by an unbalanced force"). In the case of automatic watch, the unbalanced force is the rotor.

I think of it this way...An automatic watch winds through the use of a weighted rotor attached to the watch movement. As the watch moves (from the movement of the person's arm, for instance), the rotor does not want to move, however, because its center of mass (the rotor) is different that the center of effort (the rotor shaft), the rotor begins to spin. And as the rotor spins, it winds the watch.

Now there are some things that are correct when thinking about gravity and winding an automatic movement...It's correct that in a gravity field, you can keep a watch stationary and rotate it, which makes the rotor turn and wind the watch. Like for instance in a watch winder, which definitely WOULD NOT wind a watch in zero gravity. BUT that's not the only way you can get the rotor to turn...Imagine placing the watch flat on a table and pushing it back and forth. Of course the rotor would turn, but you haven't involved gravity in the least...you are using Inertia.

OK...this has become way too geeky of a discussion...but that's how I see it."

Tourbillon to counter the effects of gravity?! In this case... zero G?

Ya this was my thought too. In addition:

In horology, a tourbillon is an addition to the mechanics of a watch escapement. Developed around 1795 and patented by the French-Swiss watchmaker Abraham-Louis Breguet on June 26, 1801, a tourbillon aims to counter the effects of gravity by mounting the escapement and balance wheel in a rotating cage, to negate the effect of gravity when the timepiece (thus the escapement) is stuck in a certain position.

So you can think of deep space as a tourbillon :D

but tourbillon only works on earth.
it's to counter gravitational pull.

so it doesn't work in zero-g?

bro xuan. The cash that I kept was supposed to buy Seiko Sumo.
But its too big for my cute wrist=:p So I thought lets just keep it to buy something else.
On the same day my partner wanted to go Mustaffa to get frozen stuffs to top up. So ok loh ... go loh
After finished purchasing go to watch corner just to see2 look2.
Hahaaaa ... end up bought one ... Orient Mako =:p :s22:

Maybe you want to look at Mustaffa. They got nice Orient and some other watches as well.

Thanks for the tip! Been a long time since I've been there. Last time is to check out fountain pens haha, my old hobby.

In deep space no gravity so no need tourbillon. I was just joking that deep space is like tourbillon, remove effects of gravity haha......
