Hey guys. So I picked up the new hesalite 3861 over the weekend and got a bunch of questions from people if the new style bracelet will fit on the old style 1861 case.
Because I own both watches, I decided to perform the bracelet swap to answer the question and show you guys the fitment. To skip the long story, the answer is YES the new bracelet will fit the old 1861 case with no problem. I used the spring bars that came with the 3861 for this exercise and the end link fitment seemed almost perfect.
Please see the below shots:
This is a back shot of the new 3861 case with bracelet mounted:
Here is the 1861 on TOP and the 3861 on BOTTOM:
Here are some side-by-side case comparisons of both watch cases (1861 on right 3861 on left):
You can see how the side profile lug shape is different on the 3861. You will also notice the 3861 case height is slimmer.
And BEHOLD, here we have the 3861 bracelet mounted on the 1861 case:
And here is this configuration on my wrist:
I estimate Omega to charge $800+ for this new 3861 bracelet independently should you want to purchase this as a separate item to upgrade your 1861 case. The alignment of this bracelet to the case is pretty much perfect from what I can see and wears quite comfortably, although I personally still prefer the Ed White flat link bracelet but I have confirmed that the case and hole position of the new 3861 case will NOT allow for the flat link to be installed. I tested this with both the Speedy Anniversary end links as well as my Uncle Seiko end links with two types of spring bars.
Best of luck to all of you on your decisions to either invest in a 1861 or new 3861. Either way you cannot go wrong but I hope this pictorial will help you regardless.
Cheers,
M
