Guys, it's a group buy invite for 22 mm BT springbars. If any of the forum member missed out like me or want to get some, please put your name and required quantity below. Our mate sputim would arrange for it.
I start with mine:

Rainmaker 10 pieces

Thanks sputim for the kind gesture ...

Hey guys. Thought I'd drop in to say hello. Also wanted to share some analysis of 20mm spring bars I've "discovered".

 

For the past couple of years, I've sworn by ST (Startime) spring bars. Unlike most rep and aftermarket bars, the springs don't crumple, the ends are nicely rounded, and they are made in Switzerland. They really are terrific.

 

But I have an account at a part supply company called Beco-technic in Germany. I've ordered stuff from them a few times, but never thought of trying their spring bars until my most recent order.

 

To my surprise, they are superior to ST bars and I suspect genuine Rolex bars are made by the same factory.

 

Side by side, the ST bars are nearly identical to the Beco-Technic (BT) bars. The ST bar ends are rounded, and the BT bar ends are conically tapered:

Now here is a comparison of the BT bars (on the left) and gen bars (on the right). Both ends are conical:

Keep in mind, that these observations are based on a random and very small sample size and no two spring bars are identical .

 

Now here is a shot of all three together (ST on left, BT in middle, Gen on right:

Conical or rounded, I don't think anyone will care. But a more important contrast is the strength of the internal springs. I've always found the ST springs are "noisy" when compressed. The BT and gen are much quieter.

 

Further here is some VERY unscientific measurements of the force required for full compression (using a kitchen scale).

 

The gen bars, are not new, but measured 506 grams on the scale; equivalent to 4.96 Newtons (if my math is correct. I have a Physics degree but I don't remember jack [censored]):

The brand new BT bars measured a whopping 580 grams (5.68 N):

And finally, brand new ST bars averaged 380 g (3.72 N):

Had the gen bars been brand new, I imagine the springs would be slightly stronger.

 

At any rate, I think my go-to bars from now on will definitely be the Beco bars.

 

If you try to order from them, keep in mind you will need to be approved. Also, I had a lot of trouble accessing their website recently (www.beco-technic.com). I'm in Canada and could not load the page for unknown reasons. So I changed my IP address to Germany and it worked fine. Odd.

 

Frankly, I think 20mm ST bars (or equivalent) are just superb for any watch that accepts them. But the BT's are as close as I have ever seen to what you would get from RSC.

 

Thanks for the info !! You are in Canada ? 

Happen to have any extra kicking around ? I'm needing 2 sets of bars lol was actually online last night looking lol

So I tried to order from the link Bart posted above. I guess it's only viable options for members in Europe. Because the shipping alone is costing me €45 to Australia. But as Bart mentioned, there's no minimum order requirement.

They have shops in HK and Singapore. Perhaps they could ship from there ?
