Daytona Stainless question

[Hvac]

Need an answer to a question. Does the Daytona Stainless model have the new adjustable clasp that can be adjusted on the fly without changing links? I've heard it does and it dosen't and I've heard it did for years and now dosen't and I've heard it didn't and now does

If it does in fact have it now, when did they start putting the adjustable clasp on? Which year and also which serial (did it start with Z serial?)

Thanks in advance!
