Oysterflex Sizing Clarification

[dpt.calvin]

Hi all,

Looking to purchase Oysterflex straps with Smarty End Links for my 116500. I have a 6.5" (~165mm) wrist and I wear my Daytona with 4 links on the 6 o'clock side and 5 links on the 12 o'clock side.

According to this thread, I should go with size D and size E. But when I look up Oysterflexes for sale, each side is referenced in two letters (e.g. ED, EF, EG). I don't see any Oysterflexes in size D and size E (or any other single letters).

TIA for any help!

PS - Merry Christmas!

You want d f. D is 4 link equivalent f is 6

I wear 4 links and 5 links. I'm confused why you suggest D (4 links equivalent) and F (6 links equivalent)?

I’m confused by what you’re confused about.

If you wear 4 and 6 and get the straps which are the same as 4 and 6. (This has to be obvious right)?

Ed is the same as d Ef is the same as f.

Sorry, I mistyped in my last post (but my original post is correct) - I wear 4 links and 5 links. So shouldn't it be size D and E?

Ah, I see. So E is a universal prefix for any size. Size D is really ED and size E is really EE - is that right?

Ah in that case yes

But I’m 6.5 and I do 4 and 6 middle micro. Is it not too tight on you?

Yes this is 100% correct. I think they swapped to single lettering sometime 2019. That’s when I got my 126655 and that was the way they quoted the sizes.

I'm wearing my Daytona as I type this. 4 and 6, also middle micro. I can fit one pinky in. It's winter, though. Maybe it does fit a bit tight in the summer (my memory doesn't go back that far, ha!).

Maybe I've lost weight since I last measured my wrist at 6.5" and am closer to 6.25" these days?

One other tip. Make sure you let them know in advance you won’t accept lug nics. My 126655 had three in the end one from rsc! Oysterflex is a bastard to fit. Never again for me.

Here’s my OF thread:
https://www.rolexforums.com/showthread.php?t=831026

From what I could determine- the double letters were replaced by single letters.
For my 7 inch wrist (and other Rolex link counts) an E and F should have been the perfect fit. But, I don’t think Rolex accounts for the fins popping up off the wrist (unlike a bracelet would). So I needed to go one size up on one of the OF’s.

I’ve seen so many stories about this same problem. Damaged lugs from trying to install an oysterflex.

I wish Rolex would equip the oysterflex straps with quick release springbars that’s become very common in other brands.

Letter number corresponds to number of links.
E and F is default for Daytona and will fit a 7 inch wrist.

6.5 inch would likely be D and F with some micro adjustment.

I thought lug nicks were normal?

After watching this YouTube video, I think I'll do it myself and tape up the lugs with electrical tape.

Usually they won’t sell to you unless it’s an exchange. Regardless good luck with it. Even rsc watchmakers have trouble.

Just bought one the other day, they let me keep the old one. In the past if the watch was under 2 years old and no wear, they will do a free exchange but they keep the old strap as long as you bring the warranty card along.

Its easy! You can indeed tape the lugs if are unsure about your skills with the springbar tool

I’ve done pretty well in the past. I now use a Nam Hing tool, which works great. But people keep saying the OF is a PITA to put on.

Have an aftermarket Oysterflex that have use on my Sub and BB58 and they are not that hard to install or remove

Ohhh, I’d be interested in an aftermarket OF for my BB58. Link? TIA!

I have a 6.5 inch wrist and have an 116500 and an 116509 in oysterflex. For the 116500 I have 4 links/5 links at 6/12 o'clock with the clasp set in the loosest (3rd) position. This translates to a D/E at 6/12 o'clock with the clasp set in the loosest (3rd) position. My recommendation would be to follow the oyster link to oysterflex conversion chart in the link the OP posted in their original post and not use the Rolex measuring tape.

Sorry, I meant 116519 and not 116509 in my previous post.

Hello, new here, but I have the 116500 with smarty end links and aftermarket rubber strap, rather than the OE Oysterflex from Rolex.

My buddy is local AD and they will not sell a customer the OE straps unless you have a piece that originally came with them.

I spent $30 on aftermarket rubber and it looks great. You won't be disappointed!

Cheers.
