VSF 126610 Submariner with VS3235 Latest Movement 72 Hours Power Reserve

I don't claim to be an optics expert by any means. I would not think that there should be any issue with the black hole effect, in fact, it may enhance it a tiny bit. Here's why:

An anti-reflective coating is meant to do exactly what it sounds like, diminish the reflection of light from a surface. Depending on the thickness of the coating, it can reduce this to near zero reflection from most viewing angles of the surface.

Sapphire crystals, being clear, actually have two reflective surfaces - the top and bottom of the crystal both will act as reflecting surfaces to any light that enters the crystal from the outside. So with no AR, light entering the crystal is actually reflected to your eyes from both surfaces. Single layer AR on the outside is the more effective of the two, but is prone to scratching. Some watches do it to the inside of the crystal to prevent the scratching on the outside. Therefore, you still get the reflection from the outside which will be a little more than from the inside of an uncoated crystal. The AR on the inside will diminish the reflection of incoming light from the outside world, as well as from the dial if it is polished. One thing to keep in mind here is that since the crystal is clear, the coating on the inside will also diminish the reflection of the incoming light from reflecting back to your eyes from the underside, but will do nothing to the external uncoated surface. This is why it looks a little better on your PAMs, but the light reflecting from the outside of the crystal is going to cause most of the glare you still see.

As for a true black hole crystal, the AR is applied to the outside of the crystal, but only underneath the cyclops itself. So light passing through the cyclops will actually be passing through two layers of AR (outside and inside) and therefore possibly enhance the black hole effect a slight degree more than the 116610 crystals which only have the AR on the outside under the cyclops.

Nicely summed up!

I’ll have a look now. It’s dark here so will be with a halogen...give me 20.

Edit:

Not a great comparison, and nothing too meaningfull here I'm afraid.
A more accurate and controlled shoot is required I think.

I tried to swap the ARF for the VSF without moving the phone.

I don't have great light available and its cloudy in the UK for the next 6 weeks.

Edit 2. Perhaps it is better to show a section...

Looks like there may be some AR on the bottom side of the 126610. You can clearly see the triangle 12 marker reflected on the 116610 dial next to the 11 marker. There's a hint of the triangle marker next to the 11 marker on the 126610, but nowhere near as pronounced as the 116610.

Notice the reflection of the date (the 9 in the date window) on the 116610, but looks to be absent (the 13 in the date window) in the 126610. I think this definitely points in the direction of there being some AR coating on the 126610 crystal's underside.

Good pics and thank you for posting them.

I’ll have another look tomorrow. Hopefully the weather will afford me some better conditions, and I’ll shoot with an SLR as well.

I see the biggest difference around the date reflections as well, but I also wonder if this is a result of the better black hole effect on the VSF vs the ARF crystal?

I just checked and compared my 126610 LN with my 5 year old Sea Dweller under a halogen light and it definitely has NO AR. The magnification and color of light bulb in the crystal is the same in both watches. I think I know what I am talking about, I used to do AR for AP some years ago.

It could be, but the other thing is the multiple reflections of the rehaut above and below the minute hand on the 116610, but just a faint reflection on the 126610. Neither of these are passing through the cyclops, so would be independent of any black hole AR. So in multiple locations on the dials (minute markers, you can see additional ones for the circle indices on the ARF if you look closely), it looks like the AR performance of the 126610 is better. These pictures are a very good start to determine the AR capabilities on the 126610 and makes me optimistic.

This is good input as well, especially given your experience in the area. Are you saying that the Sea Dweller has no AR or the 126610? or both?

Both have no AR, both have the same color and magnification of the light bulb. If any of them would have AR, the color or magnification would be different. Even on Profs crystal you see a little blue shining....

This would hold true on a crystal with AR only on the underside as well, correct?

Very valuable information, thanks for your input

Just a quick post. Just GL'd a VSF 126610LV. The clasp was H7Z. Everything looked great. But because of this thread, I asked my TD to ensure that it was the latest batch. He assured me that it was.

The VSF 126610LN that I purchase two weeks ago had the 1LQ clasp.

I understood that the 1LQ is newer and someone also said it had better finishing and a narrower clasp (.5mm)
I had to re-finish my H7Z as I found the edges a little sharp.

Ordered from Trusty. Shipped Jan 6. Tracking updated today Jan 13 showing release from customs 4 days ago on Jan 9th. Customs release time is also 4 hours before airport arrival ???? Not in DHL or USPS tracking systems yet.

The release could be because the pre-entry paperwork cleared as this is sent in advance and allows customs to clear packages before they land and speed up the processing of goods process.

I received QC pics today and my clasp is 1LQ

It would be interesting to see a macro shot of the LEC on the 126610:

The crown on the new 2020 124300 OP 41 has the LEC indicating AR on the underside of the crystal:

Yes. I've been following the bracelet debate on this thread... that's why I asked the TD to confirm. I reminded him that the LN that I just purchased from him had the 1LQ bracelet. He then confirmed that it was the "newest batch." Being that everything looked good and he quickly answered that it was the newest batch, I didn't feel like I needed to push it or RL just over this.

Is there anyone else who recently qc'd (within the last week) whose bracelet is the H7Z like me?
