Eddie inspired me to fit the Waffle Rubber black strap to my black faced Steeldive SD1979. Pretty close homage to a Squale. Have also ordered the Steeldive Tropic rubber black strap that is pretty much exactly what Squale fit as standard. Pretty good homage look as Squales cost over 1000 Swiss Francs so over 2000 Dollars. Waffle rubber strap is lighter and more comfortable than the stock Steeldive Engineer strap that is a very good strap but is heavier and you feel it more on your wrist. At 42mm I think the SD1979 is the largest I can go on my 7.5 inch wrists. Think I will try the Steeldive homage to the Seiko SKX007 now I'll have a spare rubber strap and the Steeldive 5-link Jubilee is pukka for the standard Seiko steel strap on SKX007.
