For sale ($360 OBRO) I have a Omega Speedmaster 1564/975 19 MM bracelet, reference 020ST1564975. The 1564/975 steel bracelet use the pins and tubes on the links (older style) and is part of the Speedmaster racing series watches, but it is also a direct fit for the Omega Speedmaster CK2998 (Reference 311.33.40.30.02.001), the Speedmaster First Omega in Space, FOIS (Reference 311.32.40.30.01.001), the CK2998 2018 Basel released Pulse Meter (311.32.40.30.02.001) as well as the older 40 MM Speedmaster Racing, Date and Day-Date models. I tried the bracelet on a 36 MM Omega Railmaster 2504.52 and fitted as well, so also possible to be used on the 36 MM Railmaster and Aqua Terra series of watches. Here is a link related to the use of this bracelet on the Speedmaster FOIS series: https://www.watchuseek.com/threads/steel-bracelet-for-first-omega-in-space-speedy.2503722/ The bracelet in very good used conditions as shown with a few marks and very little stretch. It measures 6 1/4 inches as shown would fit at least a 7 inch wrist when installed on a watch head. As with many other old style (pins and tubes) 20 MM Speedmaster and the 1610/930 Seamaster bracelet the newer Omega clasps with the length micro adjustments (4666, 1154 or 1159) can be installed on this band by replacing its clasp and clasp end links with either the 466, 1154 or 1159 clasps and either the 1589 or the 000015 end links for even a greater fit (the clasp conversion parts are not included but can be purchased elsewhere; if need further explanation on how to do this PM or text me for details) Price includes shipping anywhere in the USA through USPS mail, payment by Paypal. I have several positive transactions here and over 150 in Watchuseek (WUS) plus a few on The Rolex Forums (TRF) and "The Good Guys", so feel free to check them out. Also 100% positive feedback in over 1,350 transactions on Ebay under the same user name. Additional references available upon request.
