August 18, 2011: Size question and discussion.
Background information
The original size advertised was:
Diameter: 41.75-42.00 mm
Length (end of lug to lug): 47.50mm
These original specifications were based on some old measurements that I had taken from a military issue Seamaster 300 that I owned and sold long ago. The diameter I have listed above may have been based on a diagonal measurement of the case from 2 pm to 8 pm, which is my best guess as to explain the discrepancy with the figures listed below.
Based on a closer study the civilian Watchco SM300 that I bought as a reference for this project the SM300 watch measured the following:
Diameter: 40.40 mm
Length (end of lug to lug): 47.95 mm
The case I am using is one with an SLN insert and not a 60/70s case body, or at least not a 60/70s bezel, which featured tritium. As I reviewed this sample I felt that the watch should be closer to the 42.00 mm in diameter originally advertised in the pre-order. However based on the measurements of the sample watch this would mean that the watch should be increased in length to 50.00 mm to keep the proportions of the watch the same.
After feedback received from a number of forumers and customers we are here to revisit my decision. We have three sizes we can choose from:
Size: A
Diameter: 42.00 mm
Length (end of lug to lug): 49.50 - 50.00 mm
Size: B
Diameter: 41.75 mm
Length (end of lug to lug): 49.00 - 49.55 mm
Size: C
Diameter: 41.25 mm
Length (end of lug to lug): 48.50 - 48.95 mm
I will need a small amount of wiggle room on the length to get the proportions of the case just right.
First let me know what you guys think of the options. Assuming the options are "reasonable" I will put together two surveys. One for the Plankowners, which will be done in private, and one for everyone else interested in the project, which I will post on WUS. The one option that is off the table would be to keep the watch exactly the same as the original. The watch at the very least needs to be distinguishable from the original piece by size so as to prevent more fake military SM300s from showing up on the market.
