"Skinny Fat" 1.8mm Spring Bars For Diver's Watches

When it comes to securing your watch strap, the little things matter — and that’s exactly where our Replacement “Skinny Fat” Spring Bars come in.

These spring bars are precision-engineered from high-grade stainless steel to give your watch a secure and reliable connection between case and strap, whether you’re on land, underwater, or on the move.

Perfect Fit for Diver’s & Seiko-Style Watches

Not all spring bars are created equal: many diver’s watches, including popular Seiko models, use thicker spring bar tips that don’t fit standard pins. Our “Skinny Fat” design features:

• Thicker 1.1 mm tip diameter for a secure fit into the lug holes
• 1.8 mm main body diameter to reliably support heavier watches
• Stainless steel construction for strength and corrosion resistance in all conditions

What’s Included

You’ll receive a tube of 20 premium stainless steel spring bars, perfect for multiple strap changes or keeping spares on hand.

Why Quality Spring Bars Matter

Spring bars are the small parts that literally hold your watch on your wrist. A high-quality part helps prevent unexpected failures and protects your watch from damage or loss during everyday wear or active use.

Tips for Installation

For best results, use a spring bar tool when removing or installing bars to avoid damage to your watch case or strap. If you’re unsure which size you need, measure your lug width with calipers or refer to your watch manufacturer’s specifications before ordering.
