Sorry again to Cornelius from Circula for the long delay in this review. I should have goten to it sooner, because it is actually rather good. Not cheap but definitely with more in common with more expensive peices, rather than cheaper ones. Cheers, Jody

Sellita is thanking ETA everyday for the boost in pumping out those SW 200 movements
 
I almost got one of these, but then I saw the RZE titanium compressor for cheaper and got it.
They are using vintage super compressor technology, they brought it back to make these watches. I think that’s worth something. I imagine it’s a PITA to make these, so I don’t mind a little extra cost. I did think Circula was higher than needed though. Then again, I’m not an expert in the watch design and tooling business.

Some of the topics covered in this caliber listing: 4 Grades of SW200-1 Sellita Date Codes Crown/Stem Removal Ratchet Wheel Issues What is it? How to diagnose a broken ratchet wheel?

4 GRADES OF SW200-1: Just like the ETA calibre 2824-2, there are four grades of the SW200-1 movement: Standard – adjusted in two positions; accuracy of +/-12 sec/day up to +/- 30 sec/day Special (Elabore) – adjusted in three positions; accuracy of +/-7 sec/day up to +/- 20 sec/day Premium (Top) – adjusted in five positions; accuracy of +/-4 sec/day up to +/- 15 sec/day Chronometer – COSC criteria This page explains more about how Sellita grades their movements and the differences between them.

Credit: Caliber Corner © 2022, Source: https://calibercorner.com/sellita-caliber-sw200-1/ .

SELLITA DATE CODES: Under the balance wheel, near the caliber number engraving, you may have seen what looks to be a laser etched code containing DM and XYZ. DM means that the movement origin is from Sellita Watch Co (where else would it be from we’re not sure). XYZ is a Sellita code (we’re not sure the meaning, comment below if you know) As for the date part of the code, new movements produced in 2018 look like this:

DM18.1/XYZ = JAN+FEB
DM18.2/XYZ = MAR+APRIL
DM18.3/XYZ = MAY+JUNE
DM18.4/XYZ = JULY+AUG
DM18.5/XYZ = SEPT+OCT
DM18.6/XYZ = NOV+DEC

There is also a code for what Sellita refers to as “Renewed Movements”. The meaning of this still needs to be confirmed, but it appears that this is for movements that were sent back to Sellita for renewal. Perhaps brands are able to buy them at a discount. We still don’t know, but please check your movement for a two digit number starting with 2X. For reference:

Renewed Movements A 2-digit customer service code is engraved to show that the movement has been renewed. 20 for 2020, 21 for 2021, etc. Case study pics coming soon. CROWN/STEM REMOVAL: Official Sellita documentation states that the crown should be in the time setting position before being extracted. Use a 1mm screw-driver, avoid using tweezers or any other tool with a point because this could jam the setting lever and damage the setting lever spring. RATCHET WHEEL ISSUES: The primary reason behind the evolution from SW200 to SW200-1 was to fix an issue with the teeth of the ratchet wheel breaking off, perhaps while hand-winding the movement. There are skeptics who question whether these problematic parts are a direct result of hand-winding, but as with many topics in the watch community, it is a topic that is debated between those who have experienced the issue (or repaired the issue) and those who have not. Likewise, experiences with the ETA 2824-2 having similar issues is also split with some saying they have experienced it, and others pointing to how ETA holds a patent for a ratchet wheel that is less prone to teeth stripping by design.

Regardless, the ratchet wheel teeth issue that was supposed to be remedied in the original SW200 is still experienced in the SW200-1. This isn’t to say one should avoid the SW200-1, but it is advisable to avoid aggressively or excessively hand-winding your SW200-1 watches as much as possible. Aggressive or excessive force is subjective, but what is generally not as subjective is the function of the automatic winding unit, which delivers a more consistent and regulated dose of energy to the ratchet wheel. Hence, the suggestion to minimize manual (and unregulated) winding of the SW200-1.

What is it? The gold tone ratchet wheel with 63 teeth is located above the mainspring barrel. This wheel is attached to the barrel’s arbor via a single screw. It is responsible for transferring energy to wind/coil the mainspring. The energy is stored (power reserve) and released (time keeping). The stored energy is a result of either manually winding the movement via the crown, or from the spinning of the rotor on the automatic wind unit.

How to diagnose a broken ratchet wheel? The easiest way to tell that teeth have been sheared or stripped from the ratchet wheel is by visually examining it. You may also feeling of slipping when manually winding the movement. Additionally, the watch will have dramatic loss of power reserve because of not being able to transfer full energy to the mainspring. What to look for: Ratchet wheel replacement part:

If your ratchet wheel needs replace and you want to attempt to DIY, the Sellita part number is #415. Below is what the packaging looks like for a genuine part from Sellita.

REPLACEMENT PRICES: At the time of this article, replacement prices for the SW200-1 were found online in the range of $189.00 to $199.00 USD. This is for one standard grade movement. Be advised that the prices can fluctuate depending on quantity and grade of the movement ordered. If you have experience with ordering bulk from Sellita, please share in the comments below…

WATCHPRO ORIGINALS: Christopher Ward creates 21st century Super Compressor watches​

By
Rob Corder

September 2, 2020

Christopher Ward’s co-founder and chief executive Mike France is calling the launch of its C65 Super Compressor the most significant watch collection of the brand’s 15 year history.

The C65 Super Compressor brings back a watchmaking device for divers that was patented by Ervin Piquerez SA (EPSA) at the height of the scuba diving boom in the mid-1950s.

A genuine super compressor uses the patented case sealing method that increases its strength and integrity with depth, becoming even more water-tight, thanks to the technical element which gave it its name. As the diver descends, greater external pressure is exerted on the case back, further compressing the O-ring gasket. This earned Super Compressor watches a rating to 600ft.

The guy in the video says it happens if you wind it too much.:banghead: (Modern automatic trinkets have a clutch system that prevents the mainspring from over winding. Give it a good 40 full clockwise turns to fully wind it.) In my own experience I've never had a problem winding my older SW200 trinkets. On some of the newer SW200 ones the problem has occurred on brand new trinkets only wound moderately or very little. These are automatics with a rotor made to wind by the crown or wearing on the wrist.

No one is going to convince me these don't have a build issue in some of these making them fragile. I have purposely tried to wind an older MIYOTA 9015 too much or cause harm by turning the crown at least 100 times hand winding it. Not an ounce of trouble.
