Rolex 6251H “Big Logo” Bracelet - need help authenticating

[LookCloser]

Hi everyone,
I just purchased a 3.4 mil serial 1601 that came with a “big logo” 6251H jubilee. But upon inspection, I do not see “6251H” stamped under the “Steelinox”. Was this ever a common practice? Any advice/input would be appreciated. I am having a hard time uploading photos but will asap.
Thank you so much!

There were some Swiss made Jubilee bracelets manufactured in the early to mid 1960s without the model stamp, but they are mostly date stamped around 1964 to 1965. Ones that I have seen that are dated from 1966 onward have always had the 6251H stamp under Steelinox.

Your clasp blade is dated 1972 which, in my opinion, is far too late to not have the 6251H stamp.

It is possible that somebody has put an earlier clasp blade (from 1964/5) into the bracelet, but there are some other concerns about the blade stamps that make me think it needs some careful analysis.

The main issue is that the alignment of Steelinox is wrong. The 1964/5 blades have the bottom of the Steelinox stamp in line with the bottom of the Swiss Made stamp and both of them are roughly in line with the bottom of the ROLEX stamp.

This is a genuine Steelinox only blade from 1965:

Your blade has the Steelinox stamp quite a bit higher and possibly misaligned. If you look closely at the script font, sharpness of the stamps, shape of the Rolex crown, etc. you will probably find a lot more discrepancies between this clasp and known genuine ones:

The clasp blades might be from a 7836 bracelet.

Repairs using other bracelets seem quite common - especially in a 50 year old bracelet.

The “big logo” is a term for a different clasp style.

I have a 1976 stamped blade that does not have the model number on it. In the past, I have seen missing model number stamps missing from blades. It happens!

Thanks for the input everyone!! I love you guys!
I think I would agree the parts might have been cobbled together from different bracelets and the big crown clasp itself might have been from an earlier bracelet. I guess my main concern is if they are oem parts.
Unfortunately, I don’t have the ability to upload high res images here but the coroners and other Rolex motifs on the bracelet seem pretty crisp and well done in the Rolex style. I shall take it to my local watchmaker to have a look as well. Cheers everyone!
