OYSTERFLEX Sizing question: 126519LN

[Mr. Superlative]

Should I consider swapping one of the OF verticals to a different size?

My 126519 has the Oysterflex rubber strap; the 12 o'clock side has the "D" size, whilst the 6 o'clock side has the E size fitted.

Whilst the watch does wear OK, the clasp is not sitting at the centre of my wrist, but more Right. By way of comparison to my other Steel bracelet pieces; these sit perfectly centred, look aligned, balanced and wear very comfortable. See pics.

The 126 OF does not feel quite as snug as the others, however, I don't know if I should be comparing the fitment of an OF like-for-like with a Steel? I like to wear my watches fairly tight, with a snug comfortable fit.

I've not had the watch very long but am finding myself constantly messing around with the Glidelock setting, trying to find the ideal fitment.

Perhaps I'll get used to it eventually, but keen to hear from others that own a watch on an OF; how did you find the perfect size combination? Did you experiment with the OF sizing options?
