Is there a better way to run the Stop Watch: Form1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Diagnostics;

namespace StopWatch
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

    // new instance of Stop Watch
    Stopwatch StopWatch = new Stopwatch();
    
    private void lblClock\_Click(object sender, EventArgs e)
    {

    }

    private void btnStart\_Click(object sender, EventArgs e)
    {
        // Button Start Checking if already started
        if (timer1.Enabled)
        {
            MessageBox.Show("Sorry you have already started the Timer");
        }

        else
             timer1.Start();
             this.StopWatch.Start();
    }

    private void btnStop\_Click(object sender, EventArgs e)
    {
        // Button Stop Checking if already Stopped
        if (timer1.Enabled)
        {
            timer1.Stop();
            StopWatch.Stop();
        }
        else
            MessageBox.Show("Timer Already Stopped");
    }

    private void btnPause\_Click(object sender, EventArgs e)
    {
        // button reset
        StopWatch.Reset();
        lblClock.Text = "00 HR :00 MIN :00 SEC ";
    }

    private void timer1\_Tick(object sender, EventArgs e)
    {

        // Timer by hr min sec
         TimeSpan elapsed = this.StopWatch.Elapsed;
         lblClock.Text = string.Format("{0:00} HR :{1:00} MIN: {2:00} SEC", Math.Floor(elapsed.TotalHours), elapsed.Minutes, elapsed.Seconds);

    }
}

}

Class1.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Diagnostics;

namespace StopWatch.BL
{
public class Time
{
Stopwatch stopwatch = new Stopwatch();

    public TimeSpan Elapsed // class elapsed
    {
        get { return stopwatch.Elapsed; }
    }

    public bool IsRunning // class is running
    {
        get { return stopwatch.IsRunning; }
    }


    public void Start() // start stop watch
