Hello, I am new to the forum. I’ve been trying to research two hallmarks on a c.1915 Vulcain wristwatch case. There are two hallmarks/makers marks on the case. One is a crayfish/lobster the other is what appears to be the letter “H” above a pocket watch with a watch chain. I’ve looked on line and have had no luck in locating any information on these two marks. Any help would be greatly appreciated. Thank you.
