After several weeks on zulu strap, the SBDC001 is now put on the Marinemaster waffle strap. I have 3 of these straps. One came with the MM while the other 2 were bought from Katsu-san in 2004.
The SBDC001 looks perfect on the rubber strap. Some say there’s a gap in the lug when watch is put on this strap and zulu strap solves the problem. Actually, the gap is pretty small and doesn’t bug me at all. I once had a Hamilton Khaki that had a much bigger gap. That watch had its fair share of complaints on the Net as well.
