Help with Progressive Identifiier

[Dolphran]

Couldn't find this watermark in the 2013 Progressive Identifier. Can anyone help?

Circles on the 180 - Nasal side has "SM" above the circle and 153 below. Temple side has 175 below the circle and 14 below that.

Assuming S is Seiko Surmount but couldn't find any reference to the M. By Seiko's way of doing things on some lenses, the 153 could be 1.50 add and corridor "3". OR 153 could refer to Trivex and 175 on the other side is the add. 14 maybe referring to the corridor or min fitting height?

Anyway if someone could tell me exactly what this is it would be greatly appreciated.

Thanks!

Maybe a Pro Fit Optix, Acuity 11 or Identity Standard 11. The SM is related to the to the corridor length: SM=11mm, minimum recommended fitting height 18mm. Discontinued. However, the reference marks are diamond shaped, like this "<>". Referenced in the 2011 Identifier edition.

Hope this helps,

Thanks Robert, but the reference marks are definitely perfectly round circles.

Your welcome. The "SM" is temporal not nasal on the Pro Fit, but it's the only lens that had that designation. I agree that the "14" is probably the corridor length or minimum height. The add would almost always be on the temporal side, unless eye-for-eye. It's likely that 1.53 is the refractive index. I don't see any other designs that fit your criteria.
