Around the 3:45 mark. He mentions that winding the movement by the crown on ETA, SELLITA, etc.

Do not wind over 100 revolutions in sixty seconds. The maximum should be wound for twenty-five seconds. Too fast, too long is bad for the movement gears from the heat it generates. This could wear out the gears/wheel called the ratchet winding wheel.

I've been winding them around 40 times (which takes like 15 to 20 seconds) off the wrist forever and have never had any issue except for SW200. I find it a little odd that he only mentioned "SWISS" movements. :banghead: The damn Swiss must have a congenital fatal flaw. Hail Miyota!

If something is that fragile I want to find out while it's under warranty, not after.

:hmm: I guess that means you are $hiT out of luck if you own a manual hand wound trinket. Those can't be wound on the wrist.

Watch 101​

Ratchet Wheel​

The ratchet wheel sits on top of the barrel, and is attached with a screw to the barrel's arbor. When a watch is wound, the ratchet wheel turns and tightly coils the mainspring. The click holds the ratchet wheel in place, so that the mainspring cannot unwind backwards. The clicking noise you hear when winding a watch is the click tapping against each tooth of the ratchet wheel as it turns.

On self-winding (automatic) watches, a rotor is attached to the watches movement so that when you move your wrist, the rotor spins and winds the watch back up again by tightening the mainspring. A hand-wound watch has no rotor and therefore needs to be wound by hand in order for it to work.

Kinda makes ya wonder why some of these Swiss movements get all the glory, doesn't it?

The funny part is that Wing goes out of his way in this video. The RONDA R150 is the newest 2824 clone and new to Aragon. Maybe they told him when they sold him the movements the fragile nature of the R150 first gen. Even when Sellita first launched the SW200 they later came out with the SW200-1. :hmm:

TECHNICAL EXPLANATION:​

The gears on the original SW200 are following normal standards, however, Sellita found that each individual tooth has “slim geometry” and have been known to get damaged due to strong shocks to the watch. The new gear design provides power transmission equal to the SW200, but they strengthened the tooth geometry to reduce the risk of damage from strong shock.

WHICH PARTS WERE CHANGED?​

The changes to the -1 variation include making modifications to the following components of the movement:

  • Axis of reduction wheel (1481)
  • Axis and wheel of ratchet wheel driving wheel (1482)
  • Ratchet wheel (415)
Sellita Sw200 1 Differences

According to the documentation, other than the three components pictured above, all other parts of the caliber SW200 are interchangeable with the SW200-1. When performing maintenance or repair, these three components should be changed together to maintain functionality of the gear chain.

The change of version is part of our ongoing improvement strategy to optimize the performance of our calibers. -Sellita

UNRESOLVED ISSUES?​

Despite the evolution and changes from SW200 to SW200-1, the same issues are still being experienced with the teeth being broken off of the ratchet wheels/gears as a result of hand-winding the movement.

Below is a picture of an SW200-1 ratchet wheel found in a microbrand watch that was produced in 2019.

The wheel on the left was the damaged part that came in the watch. The wheel to the right was the new part ordered for the repair.

Sellita Sw200 1 Ratchet Wheel Winding Gear Teeth

To remedy this issue, you will need a new ratchet wheel. This is what an original and authentic part #415 looks like from Sellita.

Sellita Sw200 1 Ratchet Wheel Replacement Part 415 1378
Comment below if you have experienced this issue in your watch. Please be as specific as possible: brand, how often you hand wind, when the teeth became damaged, etc.

WHEN DID SELLITA SW200 BECOME SW200-1?​

As mentioned above, Sellita began this change as far back as 2008. There is some confusion online about this date because the top of Sellita’s tech sheets say “R&D 08.04.13.” This was likely a revision date. The date of the actual document was 19.08.2008 (August 19, 2008). Sellita no longer provides tech sheets for the SW200, but the most recent one we found was from 2007. We also found an SW200-1 tech sheet from 2010. Therefore, it turns out that the SW200-1 is what most of the watch community is used to.

Slop TV seems like a kiss of death for creative juices. Wing started to go downhill before the Google/Sony court case. His stuff started to stagnate. Even DEEP BLUE has become a one trick pony. They have not created anything fresh since the SHOP NBC days. They keep recycling the same old cases with different dial configurations.

It's the new collectors discovering the brand for the first time that helps keep them alive. They could not do it on just the faithful from the past who already have all of their greatest hits.

I would like to see Wing do a new collection. Totally different. I would like to see Carbon fiber, woven dials, stone dials, meteorite, carbon dials, different mop dials besides the 3 classic ones. What happen to his futuristic designs?

The imaginative artistry brainwave veins must be fogged up. I guess like rust, haze never sleeps Steve.

Wing could never do the Great Wall as good as the original Phoibos. That was my first Phoibos which led me to buy a few more. Making either of those watches does nothing for using your own creative chops. :banghead:
